I'm in Portugal at the moment, and my debit card (from a US bank) stopped working. Every ATM I have tried in the city (at least 8) says "Try another location" since Sunday, and purchases all result in "declined" since yesterday.
When I first noticed the problem Sunday, I happened across a few other travelers who were having the same problem, so thought it might just be a network problem. And at the time, I was still able to make purchases (just not withdrawals). Now I can't do either, and it's into the third day, so I'm a bit more concerned.
I called my bank, and they show no block on my account, and see no record of declined transactions. They say that my travel authorization is active, so there is no reason from their end the transaction should not go through.
I successfully made an online purchase from a US company today just to verify that my card is working.
I have a backup debit card a Bank of America, but I can't use it here, because all the ATMs here only allow for 6-digit PINs, and I have an 8-digit PIN. And I can't change the PIN on that card without going to a Bank of America branch in person.
Is there anything I can do? Is there at least a way to determine if there's a problem with the international banking network, or if my card has been blocked at some level higher than my bank (if that's even a possibility)?
