It's possible for an employee to use a fingerprint sensor to authenticate with Access PayWise+ as opposed to a passcode. To do this they'll need to:
Setup fingerprint authentication on their mobile phone.
Login to the Access PayWise+ app.
Tap More.
Tap Settings.
Tap the toggle next to Fingerprint.
This will now allow Access PayWise+ to use Fingerprint as a method of accessing and verifying their account.
