I'm so happy there are people out in the world able to reverse engineer things like this and share the results publicly. Freakin' cool.

Yeah, waiting for them to finish up so Rob Cockerham can go into a COSCO and have some fun slightly altering the price tags.

Unless they find an actual exploit, tag communication is encrypted. They would have to be using the same key. If not, one would have to swipe one of the keys, reverse engineer like this, and extract the key.
