- terinjokes 12y agoWhen I enquired my bank about my EMV card, they informed it that it preferred Chip+Signature, but that it also supported online (aka "realtime") Chip+Pin authorization. It is not configured to support offline Chip+Pin like many european cards.
- JimmaDaRustla 12y agoPIN verification is performed against the chip first, not online. Although Chip+Signature is possible, it really doesn't make sense. Edit: Chip cards provide a Cardholder Verification Method List (CVML) to the terminal. The terminal then decides what method it'd like to use. Options are PIN online, PIN offline plain text, PIN offline enciphered, Signature, or No Authentication.
- olentangy 12y agoMost US banks are going for chip and signature. I've received two new cards in the last month with a chip in them - both were chip and signature.
- cmurf 12y agoI had an AMEX Blue Business card with an RF chip in it, transaction receipts had a completely different last 4 digits using RF vs magnetic. I called to see if I could get a chip+pin and they said yes except it's chip+signature. So at least U.S. AMEX is chip+signature. However, the card's chip "pin out" area is shaped smaller and differently arranged than the one on my bank issued card. So we apparently have two different "chip" standards and I don't know which one is actually going to get used.
