Trusona supports Android version 5.0 (Lollipop) and greater. For security purposes, Trusona will only work on Android devices that passes Google's SafetyNet checks. Googles uses the SafetyNet to determine if an android device is not rooted and running a licensed version of Android. 

If you download the Trusona app on your Android device and you see this image below Trusona will not work on your device. If the Trusona app does not work on your Android device then you most likely won't be able to add a credit card onto Google Wallet either since Google Wallet and Trusona share the same security checks.
