What the Biolock is all about
The Biolock is an electronic padlock that combines a traditional lock with a fingerprint scanner. How does the Biolock work? The Biolock works by first letting the user program their fingerprint. The lock is capable of storing up to 120 fingerprints. Next, with a simple finger swipe across the sensor located at the front, the fingerprint will either be accepted and the lock will open, or be rejected and the lock will stay locked. 
What happens if the lock runs out of juice? :( If the Biolock runs out of battery power, a usb backup key is inserted on the right side of the lock, providing power. The battery compartment is only accessible when the lock is in the open position. The user slides the batteries out by pulling a tab. For any sort of padlock to be useful, it has to carry out the basic function of opening and closing as well as being durable enough to withstand someone trying to break it. If a lock cannot perform these functions, it is deemed useless. A typical padlock does not have any electronics inside, so designing the Biolock to incorporate electrical and mechanical parts that work together and making them all fit was the challenge.
