QR-Patrol is compatible with almost every device (Android, iPhone/iPad).
We’d suggest though the following minimum specs, in order for you to have the optimum functionality:

a) for Android:
– Android version 5.0 and above
– For fingerprint functionality Android version 6.0 and above

b) for iOS:
– iOS version 11 and above

If you want to use NFCs for scanning, the device must support NFC technology.
If you wish to use Beacons as well, the device should support BLE (Bluetooth Low Energy).
