my plan is to use an implant for gym access and get rid of the member card. I tried to read my member card with mobile and pc reader (NFC, hf) without success. So I guess it could be a low frequenzy card!? The gym chain uses a system by the company Gantner, to give access, closing lockers and for payment. The locks seem to be GAT lock 5000 system.
When u enter the club, they need to read your card and after that u are able to lock the doors of the lockers. The computer receives your card number during this process. Not sure if something written to the card at his moment?!
Anybody here has experiences with this kind of usage? Is it possible?
