Blessed with a unique dexterity not found in the rest of the animal world, human hands represent one of the wonders of creation. On a more mundane level they possess enough characteristics to serve as an excellent tool for personal identification. Recognition Systems, Inc., The Campbell, California-based biometric component of Ingersoll-Rand’s Security & Safety Group’s electronic access control division, has more than 200,000 hand geometry units reading the lifelines of millions of people around the world every day. The company virtually started the field of “hand recognition” technology in 1986 for time, attendance and access control, building up an enviable record as one of the world’s largest biometric companies. Schlage’s biometric Hand Readers simultaneously analyze more than 31,000 points and instantaneously records more than 90 separate measurements of an individual’s hand- including length, width, thickness and surface area-to verify that the person using the device is really who he or she claims to be. The Hand Reader compares this information with a “template” of the individual’s hand that has previously been stored in the reader, on a server or on a card. Once the person has been identified as a valid user, a door can be opened, access can be provided, or time recorded. The reading and verification process takes less than a second with impeccable reliability.
