EMV wikipost volunteers: kebosabi

What is EMV?
EMV is a defacto global standard of technology where there is a visible microchip on the front of the card. It looks like this:

Who issues them?
See Google Docs spreadsheet in Post #1

SFOAMS also has created a list of excellent webpage that shows US EMV cards in a more interactive interface

Another site, which lets you narrow the search for an EMV card by various parameters, is http://www.spotterswiki.com/emv/index.php.

Several credit unions issue some form of Chip-and-PIN credit cards or prepaid cards. Prepaid EMV cards however are not recommended due to junk fees. USAA (currently restricted to members of military) used to offer Chip-and-PIN cards, but as late has backtracked to Chip-and-Signature priority.

Hey that's a cool Google Docs list! I know others that aren't on that list. How can I help by adding them to the list?
My bad for not putting this into the wiki sooner. Right now, the Google Docs is locked out of editing and only in "read-only" view because there were instances in the past where people would just delete the rows not thinking that it affects others viewing the list.

If you promise not to delete any rows and input all the pertinent info (annual fee, rewards, FTF, etc.), I can provide you with edit access. Just shoot me a PM to kebosabi with your gmail address and I'll provide you edit access.

Thanks for helping out!


As of October 2014, no USA-based card issuer offers Chip-and-PIN priority cards except for BMO Harris (Diners Club) and UN Federal Credit Union. Other major USA-based banks such as BofA, Chase, Citi, as well as others issue Chip-and-Signature cards which may work at many automated kiosks. However, bear in mind the word may is used above is a context where there is no absolute certainty of success for certain environments such as automated kiosks due to different natures of offline and online transactions. It is highly recommended to read Post #3 which lists real life FTer examples on how Chip-and-Signature worked and did not work at various transaction environments.

Can I upgrade it right now?
If it's listed on that Google Docs spreadsheet or SFOAMS' Silk page, wouldn't hurt to call/twitter them for a free upgrade. If you get the response you don't like, hang up, try again.

What is the difference between Chip-and-Signature and Chip-and-PIN?
You insert the chipped card into the slot. The physical contact terminal will read the EMV chip and the terminal will automatically read the preferred cardholder verification methods (called CVM) for that card.

Chip-and-Signature means that the terminal will printout a receipt for you to sign. This is the most prevalent authentication for most US issued EMV cards. Chip-and-Signature helps in a way that it will get through to face-to-face merchant transactions where you and the merchant do not speak the same language.

Chip-and-PIN means that the terminal will prompt you to input a PIN for authentication. Some credit union issued credit cards will have this CVM as secondary if Chip-and-Signature cannot be done. Chip-and-PIN is the more prevalent method of authentication used outside the US, especially in transaction environments where no human interaction is needed (i.e. automated gas pumps, toll roads, train kiosks, etc.).

The Google Docs spreadsheet will list which CVM are used in the EMV cards listed. Some cards can only do Chip-and-Signature. Other cards can do both Chip-and-Signature and Chip-and-PIN. And others might have a third option called No CVM (no authentication needed) which is reserved for low value transactions.

One chip can hold a lot more data, therefore it is capable of doing multiple verification methods. That's one of the great things about EMV over the mag-stripe which can hold very little data.

I want to know for sure what my EMV chip does. Is there anyway I can test out my own EMV card to see what the CVM list is?
alexmt has written up a nice step-by-step procedure on Post #3615.

If most of the EMV cards in the US is the Chip-and-Signature type, doesn't that mean it's still useless abroad?
Depends if you see it as glass half empty or glass half full. See Post #3 for further details on how Chip-and-Signature has worked both successfully and unsuccessfully depending on the merchant transaction environment and use your best judgment whether which one is right for you.

Are there any places in the US that are accepting transactions via the EMV chip?
tmiw has created a dedicated Google maps webpage to show where EMV has been proven to work here: http://emvacceptedhere.com/ Per his Post #4240, feel free to add any places with active EMV terminals if you come across one.

As of 2014/05, the EMV terminals in most Walmarts and Sam's Clubs are being turned on. Hence, the best place to try them out would be your local Walmart or Sam's Club. For other merchants, it's slowly being phased in.

I hope people will post them in the Post your receipt of your 1st EMV based transaction in the US thread. cvarming has shown us an EMV transaction receipt from Brooklyn, NY in Post #2380. I myself had my first EMV based (Chip-and-Signature) transaction in two stores in the Los Angeles area, as shown in detail in Post #2705 (courtesy of WhatWhatTech for pointing these two stores out)

I don't want a chip in my card. I heard horror stories all over the media saying hackers can steal my credit card info from a mile away.
There are two types of chips. One is contactless and the other is contact. Cards can be either one or the other, or both.

In the Google Docs spreadsheet, the cards that are capable of contactless payments are listed seperately under the "RFID or NFC contactless chip" column. If it says yes, then that means it has the ability to do contactless payments. If it says no, it doesn't have that feature.

The one that the media has overhyped about hackers "stealing your information wirelessly" was the contactless type like this:

You are worried about this happening, right?

You don't have to worry. EMV is a chip standard that can have both contact and contactless interfaces. With the traditional contact interface, this means you actually have to physically insert the chip into a POS terminal for it to be authorized, like this:

With the contact interface, nothing is wireless. No data is sent out in a stand-alone contact type EMV chip. With the EMV contactless interface, data is sent wirelessly.

Furthermore, contactless chip cards are required to show a symbol (looks like Wi-Fi symbol) somewhere on the card that to denote it's capability as a contactless card. For example, here's an example of a Discover Card with contactless capability (in which Discover calls "Discover ZIP") showing the contactless symbol on the back of the card:

Don't believe everything that the media says. Besides, millions of people all over the world from London to Singapore, uses contactless payments daily in extremely crowded subways and mass transit with nary any problems. There are multiple layers of encrypted securities and keys that are needed to break the code.

Frankly, giving your physical card to a waiter/waitress who takes the card out of your view is much more susceptible to fraud than contactless payments.

Why should I care?
If you are an international traveler, you will want this because majority of the world has or in the process of converting to this payment format.


In fact, in 2012, even North Korea moved to the EMV format, leaving the US as one of the countries in the world that hasn't done so.

In addition, VISA, MC, AMEX, and Discover have all agreed to incentivize the USA shifting to EMV payments by 2015 by shifting liability for fraudulent transactions to merchants if they do not have EMV equipment and the cardholder has an EMV card. So if you travel internationally or would like to get one before the others, you might be interested in getting one.


BS! I had no problems using my card in [insert whereever country], [insert whatever point in time]
If you stick to the tourist path where they have lots of visitors from the US, you should have no problems using your mag-stripe only card in hotels and restaurants, at least for now. But as things can change as things go forward.

However, consider that once you start taking the off-beaten path, go to non-touristy places where they are not familiar with mag-stripes, rent a car and use toll roads, fill up gas, or try to buy train tickets you might end up into a trouble of the machine not recognizing your card because it lacks the chip. Furthermore, a lot of toll roads, gas pumps, and automated ticket machines lack any human assistance to help you when you need it the most.

But [insert credit card company] told me all merchants that display their logo must accept them! All I have to do is report them for violating their agreements, right?
There are several factors against this.

1. You can only speak English. The merchant representative, most likely a part-time clerk earning minimum wage, speaks in a different language, let's say French. If you have no French language skills, how are you going to get your point across? Are you going to whip out your cell phone at exorbitant int'l roaming charges and hope the customer service is going to translate it for you on the spot? Or maybe you might actually know French. But how about Swahili, Farsi, Balinese, or the multiple languages in mainland China?

2. Just like US, the rest of the world's businesses uses part-time minimum wage workers as cashiers to cut down on labor costs. Most of their SOP training manuals are written by MBA types to not to do anything they are not familiar with. Do not expect them to understand the intricate details of credit card mumbo jumbo. You don't expect Taco Bell employees to understand the minute details of Discover-JCB-Union Pay agreements, right? Same thing the other way around: be respectful as a guest in their country, prepare in advance in their ways, avoid being an "ugly American" stereotype.

3. You are a guest in their country. You are a minority. If 99.9% of their country's people and other tourists from around the world uses EMV, do you really think they are going to accomodate the 0.1% of American tourists who only have mag-stripes credit cards?

4. Again, you are a guest in their country. How would you, as an American standing in line, react if a Chinese tourist was clogging up the lines at a local Taco Bell because the clerk doesn't understand the Discover-Union Pay agreement and has trouble communicating between Mandarin spoken by the tourist and English spoken by the Taco Bell clerk? Same way the other way around. You do not want to clog up the lines for everyone. The less hassle, the better.

5. VISA and MC make tons of money from merchants in that country. Say SNCF French Rail. It's a billion dollar company in France. Do you think VISA is going to pull the plug of their relationship with SNCF because SNCF refuses to do mag-stripe processing at their unmanned train station kiosk? Of course not. Be realistic.

6. And lastly, if you're up against an unstaffed toll kiosk, gas pump or train ticket machine, are you going to yell curses at the machine?

But I want my credit card to be able to be used in the US too!
No worries. They have not gotten rid of the mag-stripe on the back of the card for backward compatibility reasons, just like we still have embossed numbers on our cards for backwards compatibility to using those old carbon copy imprinters.

[insert own Hyatt card image front and back together with red arrows pointing to all the backward compatibility features]

You use the chip on the front of the card abroad (for now), and the mag-stripe just like any other card for the US. Basically, you're increasing your credit card's acceptance rate by getting a card that both via the chip and the mag-stripe. You're getting a better deal for free.

And when 2015 comes along and US switches to EMV, you'll be way ahead of everyone else too!


So why did the rest of the world and the US moved/moving toward EMV?
Primarily, due to fraud concerns. You see, the mag-stripe has been with us since the 1950s. It may have been the most high tech thing back in the day, but with the technology that is available today, any shmo can pick up a $100 USB magnetic card skimming device off of eBay and get your credit card info.

And unlike skimming off contactless cards which actually need the person to have l33t programming skills, skimming off a magnetic stripe has become so ubiquitous that nary a day goes about skimming fraud going on somewhere in America, from gas pumps, Michael's stores (2011), Target breaches (2013), restaurant waiters/waitresses, to even McDonald's drive thrus.

https://www.google.com/search?q=skimming+fraud

These type of fraud used to be prevalent in Europe. But once they started switching over to EMV starting over 2 decades ago, this type of fraud went elsewhere. It went over to Asia, Canada and Mexico, Latin America, etc. etc. until they too began implementing EMV to combat skimming fraud. The US is practically the only country left that hasn't done so, therefore all the fraud that used to take place elsewhere is now happening here.


But EMV is old and it's not fool proof. Shouldn't we just skip over it and do something new instead?
Yes, EMV is old. It was developed in the 1990s and its smart card payment predecessor was first introduced in France. But as of today, it has become the defacto global standard of payments.

But then, what else is there? There is no other de facto global standard of payments alternative. For example, if we decide to skip over it and do something new, hypothetically like DNA matching technology, it still means US int'l travelers will continue to have problems abroad with useless plastic acceptance because no other country is using this DNA matching technology except the US.

Besides, nothing is fool proof. You can say that the bank vault isn't fool proof because you can crack it open if enough C4 is used. But your average low-life scumbag isn't likely to get military grade C4 easily either. But the bank vault does make it harder to get the bank's money over say a petty cash box. That's the point here. EMV is akin to a security tight bank vault, the old mag-stripe is akin to a petty cash box lying around inside the drawer.


I'm a business owner and I don't think EMV is going to take off. I'm not going to spend extra hundreds of dollars to upgrade my credit card machine. Convince me other wise why I should.
I can understand the added extra cost to your business once this switchover takes place. But before even saying that, look at your existing POS terminal. Does it have a slot somewhere to insert a card?

Most likely, if you had replaced your POS terminal within the past five years, you already have an EMV capable terminal. EMV is basically just not turned on yet from the processor and acquirer side.

If you have an EMV capable terminal, then a best bet would be to contact your acquirer to have the EMV feature turned on. You did your end of the deal already by having an EMV capable terminal, it is now the acquirers' responsibility to turn it on in accordance to the EMV switchover mandate.

And if you don't, you are going to replace your POS terminal anyway from common wear and tear. It isn't a hard switch-over. You can continue to use your POS terminal until it dies out because EMV cardholders will still have the mag-stripe on the back. And by the time your non-EMV capable POS terminal is up for replacement the market will be full with these newer POS terminals that can accept the mag-stripe, EMV, as well as contactless payments.

In addition, you may also want to check with your acquirer or processor about EMV capable terminals. Some of them are willing to replace your terminal for free in preparation for the US EMV switchover. Call and ask for details.


But what's in it for me? I'm the one that has to pay for the upgrade.
All the major card networks have given incentives for merchants for the upcoming EMV switchover.

If 75% or more of your credit card transactions are done on an EMV contact and contactless terminal, they are going to waive your annual PCI-DSS fees, which usually costs you around $5.00-$19.95/month per terminal. The overall long term cost savings of those compliance fees will be larger than the cost of an one time upgrade for the terminal.

The downside is that once EMV switchover happens and if you do not have a POS terminal that is able to accept EMV, the fraud liability shifts over to the merchant.

I own several fast food franchises. If I upgrade my POS terminals at all of my restaurants, it's going to cost me thousands, if not millions. I don't think anyone is going to use a fake credit card to buy $5 burgers. And if they do, wouldn't it be cheaper for me to eat the fraud cost?
Remember also that fraud isn't just committed by dishonest customers using fraudulent cards. Fraud can also happen with dishonest employees skimming off credit card data from the mag-stripe as in the case of a teenage McDonald's drive thru employee skimming off $13,000 of customers' credit cards in Olympia, WA. Consider the public relations fall out that your business may have if this happens (i.e. the big Target breach of 2013, where someone used a mag stripe card to load malware INTO Target's system). Is it worth risking to take such a huge PR disaster?

Simply put, when it come to doing things online where a simple software upgrade can make big changes (i.e. new points and rewards benefits, online verification, removing foreign transaction fees, etc.), the US excels at it.

But when it comes to physical changes where it involves physically changing the feature of a card (adding an EMV chip, hardcoding the PIN directly onto the chip, etc.), the US seem to have lost track on how they once used to do it.


If anyone remembers if they're old enough, I don't think it was that difficult when the conversion from old carbon copy imprinters to mag-stripes came along. But now, the US seems to have forgotten how they once did that. And the people who were in charge of that conversion are either way into retirement or probably six feet under the ground now.

I still have in the house an old imprinter which was used to imprint the raised numbers and letters on credit cards (BTW why do they continue to issue credit cards with raised nubers and letters? Nobody uses imprinters any longer). Of course even airlines used these imprinters to validate airline tickets before shipping the tickets off to ARC to process (or was it just the travel agencies that used them?). I also remember the weeklylists of disapproved credit cards which the merchant was supposed to consult before completing a transaction under the floor limit where a phone call was required for authorization (I also remember country club billing by early versions of mastercharge (not mastercard) and bankamericard (which was called chargex in Canada and barclaycard in the UK along with the signs with the blue, white and gold horizontal bands saying all cards with those colours were honored) and even receiving hard copies of the charge slips with the IBM coded holes punched in them! And I enjoyed using Diners Club the most as the credit card invoices were different in each country with it saying in the upper right corner Diners Club France and the receipt totally in French.

Yes indeed. Those were the days my friends, we thought they'd never end. we'd sing and dance...

Consumer behavior?

I think most people would rather have very secure security intact as the application makes its way through to prevent thieves from getting to use your card before it actually gets into your possession.

But who knows? Maybe times have changed where they consumers today would rather risk foregoing security and instead favor the ease of setting their own PIN at application point than the existing procedure.

"Nobody" is more like a figurative number.

The blind need it to know what their card number is. Either that or special braille imprinted cards for the blind or cards that speak out the card number upon pressing a button (latter is a bad idea).

Motels still use them for incidentals. Still was used in Missoula, MT a few months ago for incidental purposes.

Pizza delivery guy or Chinese food delivery guy relies on the raised numbers to rub the number onto the receipt.

Lots of countries where where infrastructure is still not in place still use them (still was used in a mom-and-pop store in Peru a year ago and in a hotel in Bolivia). Believe it or not, there are still lots of places in the world without electricity and telecommunications.

Yes it is phasing out. But raised numbers with carbon copy imprinters processing has its advantages that it can be done without electricity, telecommunications, or a smart phone. It has its advantages that it helps the visually impaired know what their account number is.


A great example is in a case of natural disaster where electricity and telecommunications are lost.

During the 2011 Tohoku Earthquake in Japan, those that were affected had no money to buy stuff as all the ATM machines were down for them to withdraw cash. The last resort was to dust out the imprinter and go back to the basics: clap-clap machines until infrastructure was back up.

Raised numbers and imprinters are the last resort in the order of credit card processing, so it does makes sense to keep raised numbers (though there are cards nowadays that come without raised numbers).


Otherwise, it'll be like Europe saying "why do they continue to issue cards with these black stripes on the back? Nobody uses mag-stripes any longer."

Except it'll be problem when Europeans visit the US.

kebosabi...I am certainly not going to engage in an argument with you regrding the use of imprinters. Let me phrase it this way. I have not checked into a hotel or rented a car in the last decader where pre-approval was not done electronically.

I am sure there are a few places in the third world (not meant as a derogatory comment where they don't have the ability to electronically pre-authorize or even to complete a transaction. But couldn't they just copy the account number to a payment document? Or even simply use a pencil on its side to serve to imprint?

But it's really not all that important an issue so I bow to your superior intellect on this issue.

Getting back on topic, Card Services for Credit Unions has a website now up to accelerate EMV adoption at credit unions.

I think they summarized the bullet points pretty well.


Except for this part:

"With the introduction of these products, counterfeit card fraud is essentially eliminated."

Nothing is 100% fool proof.

EMV chip can be hacked EMV: Hacked Again – Unpredictable Numbers are predictable.

EMV does make it a lot more difficult than the mag-stripe. Mag-stripes can be copied with $100 worth of parts on eBay. Cracking EMV takes a bit more effort with some genius level play by Cambridge researchers.

It's like saying the vault in the bank is fool proof. No, the vault in the bank can be blown open with lots of C4. But you don't see bank robbers with backpack full of C4 everyday either. But the vault in the bank is way safer than a petty cash lock box used by accounting.

I hope they don't get the idea that EMV is 100% fool proof. There is no such thing.

First of all, that can't work in situations where the chip card is going to be sent proactively (like it was in the Diners Club case), without regards to whether people were requesting it. That further means it goes to a lot of people who don't know what it is ahead of time.

Second, could there be a security issue if too many people choose the same PIN? If 1000 customers in a row call up the bank and ask for the pin 1234, can the bank be more liable for fraud than if the bank issued those customers random PINs? As long as the bank doesn't let customers choose their own PINs, the bank can make each PIN as random as it needs to, and can thus ensure (assuming it uses a good random number algorithm ) that no more than about 0.01% of customers (ie 1 in 10000, since there are 10000 possible 4-digit numbers, perhaps with one or two like 0000 not allowed) will have any one given PIN.

@sdsearch, the problem we're trying to solve is the assertion that people in the US don't like pre-assigned PINs and that banks don't want to install the infrastructure to allow them to change PINs.

The answer to "first" is to communicate with the holders ahead of time.

The answer to "second" is that normal course is for banks to let customers choose their own PINs (e.g., you can change your ATM PIN to whatever you want). I've never heard a hint of a claim that a bank could be liable for this.

Well said.

Even this would have played well:

"Congratulations! Your card is now eligible to have the EMV upgrade for your convenience in international travel.

You can choose one of the two options:

Option A: Chip card verification by signature aka "Chip-and-Signature."
There will be no PIN needed and it should be good for majority of transactions.

Option B: Chip card verification by both signature and PIN.
The default mode will be Chip-and-Signature. Chip-and-PIN will be used as a fall back. Please keep in mind that should you choose option B, the PIN number will be automatically assigned and cannot be changed as of this moment since it will be coded directly onto the chip. We will notify you when PIN changes can be done."



It seems banks made the decision to go with Option A, whereas CUs made the decision to go with Option B.

Well, Wells Fargo seems to be taking option B with its high-value clients, so there's some hope it'll trickle down to their regular cards.

For all you PIN lovers - check out this article:
People tend to select very bad PINs... I'd rather stick with random-assigned pin by bank or with signature authorization and no liability...

Just to be clear, there is an option C that kebosabi didn't mention (because it didn't seem to belong in his proposed letter), but that exists as a separate implementation:

Option C: Chip & PIN period. No signature fallback with the chip AFAIK. (Signature is used when the swipe strip is used instead of the chip, of course.).

Option C seems to be what BMO went with for Diners Club US. (There was no mention of using the chip with a signature in any of the materials about the card. It said you use the PIN when using the chip, but a signature when swiping the card.)

Are you sure Wells Fargo went with B and not with C for those high-value clients?

Remember that even ones with online pin won't work in countries like the UK or France and will revert to chip and signature anyway.

I am sure there are a few places in the third world (not meant as a derogatory comment where they don't have the ability to electronically pre-authorize or even to complete a transaction. But couldn't they just copy the account number to a payment document? Or even simply use a pencil on its side to serve to imprint?

But it's really not all that important an issue so I bow to your superior intellect on this issue.
I'm not trying to argue, just discuss.

Taxis are where I regularly encounter imprint machines in the US, and most shops seem to have one as a backup in case their credit card terminal goes down. I had to write up my own slip and imprint my own card at a Steak and Shake a few years ago because nobody there knew how to do it and their system was down.

They're also critical in areas like where I live in florida for whenever there is a hurricane.

The reason why copying the account number down instead of imprinting isn't preferred is that the imprint proves the presence of the card. Card present transactions (mag swipe, imprint, etc.) incur lower merchant fees than card not present transactions due to the lower risk of fraud when the card is physically present.

You'd think that services like Square would be more common with taxis rather than imprints.
