Biometric verification is any means by which a person can be uniquely identified by the evaluation of one or more distinguishing biological traits.
Unique identifiers include:
- Hand geometry.
- Earlobe geometry.
- Retina and iris patterns.
- Voice waves.
Advances in biometric verification have been considerable since their first use and the advent of computerized databases and the digitization of analog data allow for almost instantaneous personal identification.
Net1 makes use of fingerprint biometrics stored on the smart card through the card enrollment process, these fingerprints are then used to biometrically verify the card owner before card transactions can be performed. Net1 ATMs and POS devices have integrated fingerprint scanners to perform this function. Net1 has patented an "emergency finger" methodology that allows a U.E.P.S. cardholder to minimize the amount of money lost when performing transactions under duress.
Net1 also makes use of its own Automated Fingerprint Identification System (AFIS) in certain systems to weed out duplicate cardholders and identify possible fraud through a unique, internally developed one-to-many search engine.
