Hand geometry measures the size and shape of a person’s hand, including length, width, thickness and surface area. When the user places his or her hand on the platen of a device like the Schlage HandPunch, the device scans the hand to determine if the profile stored in the system matches the hand on the platen. In many cases, a swipe card or PIN may also be required to allow access.

• No fingerprint or palm print is stored in the device.
• Data is not shared with any outside agencies or companies.
• Verification takes place in about one second.
• Unauthorized access is eliminated since credentials cannot be duplicated.
• Since the “credential” cannot be lost or stolen there is no cost to replace lost, damaged or stolen cards or keys.
• Hand geometry accurately identifies the user even if his or her hand is dirty, wet or injured, or if the device is damp, dusty or dirty.
