Just re-confirming that it was fairly easy to get a VISA Debit Card at Taishin. Went to the local branch with Passport, ARC and drivers license and it was fairly straightforward.
If you are content with a card that does not have your name printed, they can give you one on the spot. For a card with your name printed, expect to wait up 7-10 days.
-> The card is marked "Electronic use only". Don't worry. This just means that it can't be used in situations where instant electronic approval isn't available. These days, that basically means you're in one of two situations:
1) The store's phone line has died and they want to use an old-school "knuckle buster"  machine to take an "imprint" of your card. This won't work because your card doesn't have the embossed characters on it.
2) You're on an airplane. (they might still accept the card accidentally, but they're not supposed to)
-> The card doesn't have a visa PayWave chip
-> By default, it will not be enabled for access overseas. Just ask for that to be enabled, and they'll inform you about the withdrawal/overseas fees and switch it on.
When you get your card, you'll be in a branch anyway, so head straight to the ATM. Go to the service/function settings section and update your PIN. You need to do this to activate the card. The card has two PINs - a 6 digit one for local use and a 4 digit one for international use. If you can update your 6 digit PIN, but not your 4 digit PIN it probably means your card was not enabled for overseas access properly, so go back and fix that.
Oh, and ProTip: If you forget your Internet banking username/password, you can use your card in the ATM to reset that. If you ask at the counter, I think there's a 50NTD fee
So far the card has worked online at PCHome, in-person at Carrefour and at the Taishin ATM to get cash out. Will be trying it overseas next month.
