Bank cash machine cards
Finicky things, cash machine cards.
It's a good idea to have a couple of cards from different banks. Only one needs to have the cash in it, so long as you can transfer funds quickly by internet-banking, into the second.
This way, if the first card dies or disappears, you can still draw funds using the second card, following a trip to the local internet cafe, and a wait of a day or so for the transfer to be completed.
You could always leave a small amount in the second card, so remove the need to wait for the fund's transfer.
