QR code usage counter in Glide without Scanner (Explorer plan)

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.
