Building Locks
I started building a new digital lock recently, a disk lock for lockers, storage units and the like. These will not use a key, rather they will use a key fob or RFID touches electronic system for fast secure opening. More coming soon about the commercial availabilities of these new padlocks.
With my new locks there is no more vulnerability to lock picking. No more loosing keys, and a host of cool options like solar charging, powered by your phone, RFID, NFC, Bluetooth, USB charging and more.
