The insides of an Oyster card

The insides of an Oyster card, originally uploaded by ka-d.

Was shown this by Timo Arnall the other day. It’s an Oyster card (Londond tube card) that’s been etched in some kind of acid, leaving only the RFID tag and antenna. Apparently it still works. I find that fascinating.
