I got one of these guys watches, it has an RFID chip but I can’t think of anything to do with it.
It looks really cool though. The light is nice too since its bright enough to use as a flashlight when its dark enough.
- varikin 5y agoI use to work at a place that included parking in rfid activated ramp. I always wanted to clone my badge into something sewn into the wrist of my motorcycle jacket so I didn't have to fumble for my badge while entering and leaving the ramp. In a watch would be perfect.
- peanut_worm 5y agoHow would you go about doing something like that? Are RFID chips that insecure?
- jsmith45 5y agoRFID and NFC are complicated. At the high end of NFC communication you have the basically the same chips used in smartcards (like payment cards/sim cards/etc) running with limited power, but theoretically able to run all the same apps. These can be cryptographically secure. At the other end, a lot of rfid tags are very easy to just read and clone, including many involved in access control systems. These often just work based on the uid number that is freely readable, and most of the protocols have chips available where the user can write this "globally unique" id that would normally be written by the factory.
