Biometric Time Clock Identification
There is a fundamental rule of personnel identification that is often overlooked:
CARD READERS CAN'T IDENTIFY PEOPLE
PEOPLE CAN IDENTIFY PEOPLE
DOGS CAN IDENTIFY PEOPLE
BIOMETRICS CAN IDENTIFY PEOPLE
And Biometrics does it best!!!
Biometric identification devices use as a key a characteristics sch as hand geometry that is unique to the individual. For the first time, true automatic identification is possible. With hand geometry, it is the authorized person who is identified, not merely the cardholder, thus assuring the ultimated in accuracy of Time and Attendance records.
The HandPunch is a biometric identification device that uses a three dimensional image of the hand to uniquely verify a persons identity. This image is acquired by a television-like camera. They system is small, simple, quick,a no has no moving parts.
The HandPunch contains a digital camera which records a picture of the hand, and a microprocessor which extracts identity discriminating characteristics from the hand picture. During the initial enrollment process, 3 hand measurements are made with the results averaged. This forms a template of the user's hand which is stored for later use in identify verification. The stored template is automatically updated with each successful use. This assures that changes in the hand that occur over a period of time are accommodated for. This may sound sophisticated, and it is is. But it is also simple and quick.
To use the system, the enrolled user enters an ID number via a keypad - normally the last 4 to 6 digits of their SSI or SSA number, or their birth date. The system prompts for the hand to be properly positioned, takes a tv-like picture. The identity discriminating characteristics are extracted from the picture and compared to the previously stored template. The results of the comparison are displayed in about a second. the resulting signal can be used to simply list the employees punch time, or even to send a signal to an access control relay and verification program.
