Surely the bosses paid extortionate salaries should be wearing these biometric devices instead, to show us why they earn such vast sums.

Biometric devices including fingerprint and iris scanners and facial recognition programmes are increasingly being used to verify identities because they are more convenient than passwords and arguably more secure.

This framework consists of a set of components that standardizes the use of fingerprint biometric devices.

All biometric devices, therefore, do not provide unambiguous guarantees of identity, but rather probabilities, and all may provide false positive and negative outputs.

The most common technologies are magnetic stripe, proximity, barcode, smart cards and various biometric devices.
