Disadvantages associated with fingerprint door lock systems
Fingerprint based systems while very useful do however have some disadvantages. And ironically enough, many of them stem from the system’s very virtues. While they are very, very hard to fool, it is not impossible. Scanners that use optical systems to obtain information can sometimes be fooled by an image of the finger. On the other hand, a person can get around capacitor based scanners by using a mold. These situations are avoided by using pulse and heat detectors also called live finger detection.
Another major issue with Fingerprint based door locks is that if someone does manage to create a copy/mold/image of your hand that can open doors, well, you are in deep trouble. Since you can’t really reset fingerprints the way you can with a normal password, it will mean either replacing locks or using a combination of pin and fingerprints.
Also, sometimes the scanner may refuse to recognize your finger in case of scarring or cuts or abrasions. Power cuts, battery discharge are other common issues associated with these door locking systems, which have the potential to leave you stranded outside your workplace or office. They are forestalled by integrating a mechanical system, where you can use a key to unlock the door in case of such a failure.
