That will probably visibly damage the card (I expect the loop antenna would get really hot) and it would disable the chip-and-pin feature as well, making the card useless.
I've had a MIFARE card crack starting from an edge, sectioning the loop antenna. I couldn't get it to work again even if pressing the two sides together, and it wasn't visible unless pulling the two sides apart, so this seems like a better approach.
- femto 13y agoIt would be an interesting experiment to try and do it closed loop, in an effort to dump enough energy in to damage the radio front end, but not overheat the rest of the circuit. Have a computer with a card reader interrogating the chip via the near field, and cutting the power to the microwave, via a relay, as soon as the chip stops responding?
