So, I bought a card reader just so I could look at my cards for curiosity:
1. American Express (BCE and Costco) have no CVM list, as we knew.
2. Chase Sapphire Preferred and Citi Forward are signature then no CVM. PIN only in the list for cash advances at ATMs.
3. B of A Travel Rewards has online PIN for purchases in after signature. It's a chip and PIN (online) with signature priority. Oddly, it is set to move on to no CVM if supported on PIN failure, meaning the WRONG PIN could still work...
