The device seems relatively easy for an employee who has never used fingerprint readers before, very intuitive in how you access your PINs/passwords or other personal information (even though we are using them rarely). I have heard that they do not work well with certain phones like iPhones but don't know much about their compatibility so take my word at its only "limited" support if any issues come up! We use these because our biometrics were being stored elsewhere by another vendor; hence why there was no security risk until now when someone did manage to steal one from us during moving day without detection due to poor storage practices within past years' contracts between vendors involved heretofore!!
