Adalo QR scanner has a function behind, so you add actions to create records/update. Your scanner even if reads the QR code, will have no effect on ADALO, just for the system it is connect to. Barcodes also have different encription than QR codes.
I wanted to do a management system for warehouses in the past, and I remember I found a scanner with an android system that worked when I installed the apk on it.
Thank you @Yongki for the response.
