Fingerprint scanners used to unlock doors are nothing new, but a little modification in this concept by designer Dongsuk Seo has made fingerprint scanning a little bit more efficient. Dubbed the Grabit, the fingerprint scanner has been fitted over where a lock would normally be. It has also been positioned in such a way that users wanting to open the door can grab the handle with their thumb over the scanner, allowing the machine to scan their thumb and unlocking the door almost instantaneously. This is a step up over some of the current systems where users will have to wait a while for the machine to recognize their fingerprint and make a separate action for opening the door itself. Unfortunately it is merely a concept for now, but given that fingerprint scanners for doors can’t exactly be considered to be new technology, we wouldn’t be surprised if it eventually found a way to be implemented.
