Hi! I am developing an app for a charity event in my neighborhood where a qr code is generated as a ticket for attendees, I have a view where I scan the qr code and it brings me the data. But what I need is that when a qr code is scanned I can not scan it again or do not allow that person to enter or delete the data of the person so when I scan it again does not bring me the data of the person.
The data to generate the qr code is also inside the application, it is a code generated from an ID and the document number of the person.
You could add a Y/N column called ‘Checked In’ and set it to ‘Y’ once the QR is scanned - either using an expression in the initial value along with reset on edit or manually in a quick edit column, and then have a slice that is filtering out Y/N values, which your QR code will direct to. If the QR code has been scanned, and the new column is Y, it will no longer be in the slice, and scanning it again will no longer be able to direct it to the correct view.
