As stated before almost all banking app could dictate that a particular device had been used to register the app this is due to the fact that each device contain a specific ID which is used to identify it for each current season.

So a token is generated by the device or ID which the app sever recognizes and that token is saved within the device storage so when next it sees the system it tends to identify it.

But once the device undergoes hard rest all the information held by the device secondary storage is lost so the initial ID is lost and must be regenerated.
