Photo ID Cards
I sure wish DC would provide the photo ID's (e.g. your photo on the face of your credit card) like Citibank Mastercard does. I get asked for ID almost everytime I use a credit card here in California. It's so easy when the positive ID is right on the face pf the card rather than having to produce my driver's license.
I asked DC about it and they simply said they don't offer it. Maybe if enough others contact them with the request they will offer it. It's not only convenient, but it makes your card more secure.
