Not a good idea.... We had a biometric scanner system linked to our payroll system... you clock in and out with a finger print scanner.. but some of the guys { those who did handyman jobs and work

with their hands a lot } had problems with the system not recognizing their fingerprints. The other problem --> People will know that your finger print is the way to access your money and they would

simply force you, with violence to give up your money.. A password memorized and written down as a backup in a safe place, will never be trumped by Biometrics.
