Hello, I have a Project where I need to clone an RFID badge (for a parking entrance). I try it with RC522 module but it dosn't work. The 2 badge have the same UID but not the same SAK. The original one get SAK 88 and all new have SAK 08.
Does problem come from SAK?
Is it possible to change SAK?
If you have any idea do not hesitate to send them to me, it would be very useful to me.
Thanks all for help
