Seller, storekeeper, technician, courier, doctor — everyone gets their own ezze screen on the phone. Camera barcode scanner, photos, works over Wi-Fi and the internet.
iPhone: no app needed — point the camera at the QR code in the program and the screen opens in the browser (shop Wi-Fi only).
Android will ask “Allow installs from this source?” — allow it. If Play Protect warns you — “Install anyway”.
In the ezze program: “Settings → Staff screens → + Connect a phone or tablet”, choose the role and the employee — a QR code appears.
In the app tap “Scan QR code” and point the camera at the computer screen. Done — from now on just open the ezze icon.
