Steve M: So What happens at Walmart when the Amex being used is not U.S. issued? How is the transaction approved/ verified? Only U.S. cities/ towns have zip codes. </font>
I almost included this question in my original post. I have no idea. Perhaps they go back to their previous practice of asking for photo ID. I would imagine that their register system could differentiate between a US and non-US Amex card by the first few digits of the card number (assuming of course that they are assigned in this manner), or lacking that, perhaps the cashier will just accept photo ID if the cardholder says they are not from the US. I have no non-US card and know nobody that does, so I have no way to try it out. Maybe I'll ask the next time I'm there.
