Abstract

A biometric registration and verification system and method is usable for registration, for verification and/or for participation, and may comprise: a biometric sensor for capturing biometric data; a data entry device, a computer processor for receiving captured biometric data and entered data; and a database storing records thereof. The identifying biometric data may be related to the entered data in the database record. The biometric sensor may capture verification biometric data and the data entry device verification data; and the processor compares the verification biometric data and the received verification data with the identifying biometric data and entered data from the database. If the verification biometric data and the received verification data of the person to be verified corresponds to database identifying biometric data and entered data, then an indication of verification of the person is provided.
