Meet TappLock: a smart padlock that you can unlock with your fingerprint. It has an encrypted fingerprint sensor that does the job with a simple tap. Since TAPP has Bluetooth, you can manage it from your smartphone. You can store up to 100 fingerprints and choose the time, location, and duration of access.
TappLock is lightweight and water resistant. The battery lasts up to 3 years on a full charge. Yet another interesting Indiegogo project.
