I want to use a Glide app to read a QR code that I’ve already generated and stored in a table, and when a user scans it from their phone, it should subtract a value from a column (for example, if the QR code has 10 uses, each scan should deduct one). But since I’m on the Explorer plan, I think I can’t use the scanner component. Is there any way to do this anyway?

Use hardware qr scanner. Usually hw scanners putting text of qr to input text field.

Can you explain in more detail what the steps would be for a hardware QR scanner to write into the database?

Connect hardware scanner to Glide device. Arrange only one text input field on screen. When you pess scan button on hw scanner it emmediately write text to “on screen text field”.
