Boarding Pass scanner at security: do they detect one pax going through twice?
I witnessed the following conversation between two travelers approaching the Accès No. 1 lane at CDG 2F:
"With your boarding pass they won't let you into the fast lane. Here, take my printed boarding pass, it says Sky Priority, and I use the one on my phone to go through". The lady doing the checks at the entrance of the fast lane probably only checks if there is a red SkyPriority square on the printed boarding pass or a red line on the mobile boarding pass, but she doesn't read names. But what about the scanners that are just by the X ray machines and where they scan BPs at the moment pax put their stuff on the belt? The scanners at boarding gates obviously check against the pax list and detect any double boarding, but do the scanners at X ray machines also register who went through and if that same person for the same flight already passed through 10 seconds ago?
I think the scanners register it for some sort of "conformance" (which is not a public rule at CDG, but airlines seem to use it nevertheless), but not sure.
And in any case, it would have been easier to just "guest" that person without Sky Priority access. I have done that several times in the past, never a problem (it was with family members, maybe that made a difference).

I have done it too, but AFAIK guesting is not a published perk, so we are at the mercy of a security employee who says "no".

EDIT: got it, I just saw that you are located in the USA. Well, in other parts of the world things sometimes work differently than in the US (shocking, but true). This thread is about Paris. There is no matching of ID and BP the same way the TSA does it when you enter security.

Beside conformance, it could be used as a partial/soft security mechanism. That has been my experience at MAN several years ago (long before "conformance" was introduced at LHR), when I was still a smoker : my flight was delayed so I decided to go back out for a smoke. When attempting to re-enter airside, the BP reading machine rejected my BP as I was still airside as far as the system was concerned and the airport agent growled at me for having come back landside after having gone airside.

Incredible things happen outside the US indeed. I remember a nice American lady expressing her surprise that "only foreign currency was accepted in the hotel " in Chile, so she had to change her US Dollars into Chilean Pesos.

A recent one was the guest from the US who thought it strange that the power sockets in the room of a hotel in Sydney (Australia) were all of the Australian variety, and even worse the hotel didn't have an adapter presumably for every other plug type in the world

Incredible things happen inside the US too! Practically every day I meet new Europeans who apparently have never seen a street grid! "Where is 14th Street?" they ask me, standing under a street sign that says "15th Street" with "16th Street" clearly visible in the distance.

FWIW Air China (Star Alliance) gave me a generic Acces n°1 voucher at CDG1 the other day when travelling with them. When you scan your BP the access is refused but when scanning the voucher you can enter as many times as you want and the machine displays this message "Manual access".
Then no problem at security or at the gate if your BP was not scanned.

Oh don't get me started...
