Not being a hi-tech kind of person, but this sure looks interesting for people who want remote locking, blue tooth, ect... and it is TSA approved. This lock will even tell is it's been tampered with, opened, has a locator , and alarm feature. Hopefully the link works, but the lock is called " AirBolt ", a small luggage locking device. https://www.touchofmodern.com/sales/airbolt/airbolt
