But only if you're as dim-witted as I am.
I always use my debit card to get foreign cash. It's always worked great everywhere I've been.
The other day, after my fifteen hour flight to hkg, I tried to get cash from the ATM at the HKG airport. Slide the card in, punch in the PIN (I memorized the sequence visually so I don't need to look at the key pad- my code is a name). Code invalid. Hum. Try again. Code invalid again. Something's up. I don't want to risk a third attempt and have my card swallowed.

I make it to the hotel by paying for the train ticket with a visa.

The next day, I walk to to Nathan Road's ATM and look at the keypads of the ATM carefully. Surprise: Instead of the usual 123,456,789,0 (starting from the top left of the keypad), I found out that the ATMs in HKG have 123 on the bottom row, and 798 on the top one!

I could have been cashless for my entire trip. So if you're as absent-minded as I am, watch out and read those keypads.
