There are several ways to keep track of your luggage after checking it in. Most of them can easily be removed should they be discovered by nefarious actors. KeySmart's solution solves this problem by integrating an Apple Find My-compatible tracker into a lock, securely attaching it to your bag. The device itself has a durable alloy shell with an integrated, TSA-approved combination lock, a rugged cable connection, and a built-in speaker that can play a sound on demand, making it even easier to locate your bag.
