How to desactivate QR Code after scan (like event ticket)

Hello, I would like to know how to desactivate the QR Code of a custommer after a scan, like an event ticket.

I need it for a Dance company, who sell dance events and need uniques QR Codes.

I used the correct code for hash the QR Code, but administrator can’t desactivate the QR Code, or its not automatic. It’s too long to go to the settings of the QR Code and desactivate it manually.

Thanks for helping me 😉
