Americans Abroad

I've been visiting for a while in the Philippines and suddenly about a week ago my debit card doesn't work anymore. Credit card works fine for purchases at stores, but leaves me with no cash on hand. So I called the bank back home and they were the ones that told me about the EMV chip, that most other countries had this technology and were rapidly implementing it, but the US eh.... not so much. Not sure what the glitch was but today our card started being accepted at ATM's again. I have to call the bank back and find out if they did something or if it was something here that was the problem. No one needs that kind of headache.
