Residential Biometric Fingerprint Locks

I have been extolling the benefits of fingerprint identification locks for a little while now, but recently I have learned by trial and error (some costly errors), that many of the more popular fingerprint scanners used in fingerprint locks have difficulty in recognizing fingerprints of people over the age of 60.

This is very unfortunate and, I suggest a serious setback for mainstream acceptance of fingerprint locks for residential uses.

The problem lies in the ability of the scanner to read the fingerprints. You see, as people age, the tips of our fingers wear, making accurate differentiation of prints, significantly more difficult.

When attempting to program a recently installed fingerprint deadbolt, I was attempting to help an 88 year old to program her fingers into the unit. The application was for an internal cupboard with the desire to make it secure, but not have to carry a key or remember a combination, a task that many elder people find debilitating due to memory loss. You cant lose your finger* though.

Unfortunately the application will require a digital deadbolt, to ensure the user can operate it.
