I’ve just got my NExT registered to be my keycard to my gym. It scans correctly, and it’s registered in the system seemingly correctly. But it doesn’t unlock the door or gates.
I’m unsure if there’s some encryption that my chip is missing, but it’d surprise me as the keycard is just a cheap mass produced rfid card.
Any suggestions to fix it. I have full access to the gym’s computer system, if needed
The purpose of using the RDC is to determine if the reader is multi-frequency. If so, the wrong chip inside your NExT might be getting read by the reader and causing it to beep, but the wrong chip ID is being reported back to the door controller.
