eGeeTouch seems to have solved a travel problem we weren't even aware we had. Rather than having to fumble with a dial code or a key that's been TSA approved, the company's keyless smart lock uses NFC and a battery that should perform for 30,000 cycles between changes. Push the unlock button to activate, swipe the included NFC badge or your phone over the lock, and then slide the catch to unlock the lock. Battery die mid-trip? No worries: You can still use the device's physical key or a USB port on the side that will power it while you activate the lock to open it. While the eGeeTouch's developers don't have any immediate plans to sell the lock as a standalone device, they're already in talks with luggage vendors to have this on the market by the second quarter of the year.
