Hand Punch Employee Time Clock Design and Operation
 

Every hand is unique. The HandPunch 1000 takes over 90 measurements of the length, width, thickness, and surface area of the hand and four fingers--all in just 1 second. The technology uses a 32,000-pixel CCD digital camera to record the hand's three-dimensional shape from silhouetted images projected within the HandPunch.

The HandPunch 1000 disregards surface details, such as fingerprints, lines, scars, dirt, as well as fingernails, which may grow or be cut from day to day.  Because the HandPunch uses the unique shape of the users hand to verify identity,  it can be used in machine shops,  factories, manufacturing plants, and almost any industrial environment where fingerprint readers would not work properly.

During enrollment, which takes approximately 30 seconds, the internal HandPunch processor and software convert the hand image to a 9-byte mathematical template, which is the average of the three readings.

Among biometric technologies, hand geometry has the highest user acceptance. With the highest level of accuracy and ease of use, the HandPunch has become the most widely accepted biometric technology in use today.

The HandPunch verifies identity at the front entrances of over half the nuclear power plants in the U.S. At the 1996 Olympic Games, HandPunch units were integrated with the Olympic Village security system to process millions of transactions, with minimum delay.

The U.S. Immigration and Naturalization Service (INS) uses the HandPunch to allow over 60,000 frequent travelers to bypass immigration lines (through the INSPASS program).

AIRPORTS AROUND THE WORLD ARE NOW USING HANDPUNCH
TO POSITIVELY IDENTIFY PEOPLE

The drastic reductions in cost of microprocessors in recent years has brought affordable hand geometry technology to the commercial market. Biometrics are no longer found only in nuclear power plants. Now, day care centers, restaurants, schools, retail stores, athletic clubs, hospitals, nursing homes, or any business can take advantage of the HandPunch technology.
