Say, does anyone have a magnetic strip reader/writer? It might have some intersting uses, don't you think? ^^^^^^
A mag-strip may be copied from one card to another with a steady hand and a dubbing tape deck. I'd hazard instead one could read the data into a computer via a sound card and edit it to taste. Then drop it back on that or another card by the same method. This works for things like library photo-copy cards. I don't know if others, like bank cards, require a stronger field to write. Also, there are probably checksums or hashes on bank/ID cards.
