One key for one lock? No, that's an old story. In the near future, home security will be digitalized. This Barcode Key is a digital device that stores all your passwords as barcodes. When you want to unlock your door, for instance, you just need to put your key right in front of the digital lock on the door. Then the digital lock will scan your key for the right barcode.
Everyday we carry a dozen of keys and sometimes find it difficult to find the right one. Barcode Key solves this problem with digital technology. It also brings benefit to blind people with its straightforward way of use.
