Why Use 3-Dimensional Geometry of Two Fingers for Highest Performance?

A) User Friendliness.
When being enrolled, users quickly understand that Biomet's finger geometry is unique and private. The 3D picture of their two fingers cannot be used with any other (criminal or other) recorded information (fingerprints, facial photos, etc.). There is absolutely zero invasion of privacy.

B) Low Cost.
Because of Biomet's speed and accuracy, the total cost of the installation will be far less than with any other biometric verification technology. Throughput of up to 10 users pre minute means fewer entry installations (turnstiles, gates, entry doors), less infrastructure, less computer power and data storage required (only 20 bytes per user).

C)  Flexibility.
Biomet's 2-finger readers can be used on a stand-alone basis with the user's 20 byte finger photo data stored on any type of entry card or in the reader without use of cards. A networked system of any number of entry/exit readers will be far less constly than systems using any other type of biometric identification or verification. Finger Geometry readers can be installed in ATMs, border "green card" checkpoints, police cars, mobile payment vehicles for distribution of public benefit funds, as well as large offices, factories, stadiums, or theme parks for entry control.

D) Totally Proven.
There is no guess work about the performance and user acceptance of Biomet's 2-finger photo technology. Developed nearly ten years ago, there are many thousands of Biomet's 2-finger biometric terminals installed worldwide with more than 50 million users enrolled. These installations range from offices, laboratories, banks, and government facilities, to the largest theme parks and stadiums for user-friendly control of season ticket holders, as well as major airports for security control of passenger identity.
 

A) Speed and Throughput.
At the rate of 10 users per minute no other biometric verification technology can come close.

B) Accuracy.
Biomet's 2-finger scanners can be adjusted to a wide range of go/no-go (accept/reject) threshold levels, depending upon the degree of security required. The curve below shows the remarkable performance levels, based upon proven first/single try use, that are achievable using Biomet 2-finger scans. Less than 0.3% false rejects and 0.7% false accept retries are required at the standard factory threshold setting of 150. To obtain near zero false acceptances a threshold setting of 240 is used, and sitll only 1 in 25 users are required to make a second try to pass. (Statistics based upon NCR trial of 10,000 user tries and a Bank of South Africa trial of 16,000 tries).

Note: Many biometric devices are quoted using 3-try statistics. The graph is based upon single try results. Also note that these tests were done without the automatic template updating feature, which would have further enhanced performance.
 

C) Counterfeiting.
Unlike fingerprints, which can be copied from a drinking glass or even a piece of paper and replicated in gelatin or latex, there is virtually no way the 3-dimensional configuration of a person's two fingers (length, thickness, shape, and knuckle-bone characteristics) can be copied and reproduced. User voice patterns, signatures, and facial photos are much easier to copy, hence to counterfeit. Biomet's 2-finger geometry is by far the most "counterfeit resistant" biometric ID/Verification Technology available today.
