"This high-tech padlock looks like an old-fashioned lock. It isn't. It claims to be the first of its kind to require no key, no dial, and no code.
Instead, a fob using Near Field Communication sends an abracadabra signal to the lock. Another option is downloading the Egee app to a smartphone. While NFC is the primary unlocking mechanism, Bluetooth is incorporated to allow for vicinity tracking should luggage go astray. The EgeeTouch lock is TSA-accepted. Pricing for the lock and matching fob -- crowdfunded on Indiegogo -- starts at $45.”
