Description : Are my credit cards still valid if I punch a hole in it (not in the magnetic strip, obviously)?
Last Answer : answer:I'm not a banker, so don't count this as a totally authoritative answer, but I would think that punching a hole for a keyring would NOT in any way invalidate a card. Why would it? As you ... almost every credit card issuer has a website that lets you do a card reorder in case it is a problem.
