Traveling is a big enough hassle without having to worry about your bags. Alleviate those concerns with the AirBolt Smart Travel Lock. Designed for use on checked baggage but good for a multitude of other things, this rope-based lock uses Bluetooth to let you lock and unlock it with nothing but an app. You can set a backup unlock code for times when you don't have your device around, set alerts that will buzz you should you and your bag become separated, and use crowdsourced GPS networks to show the lock — and therefore your bag's — last known location should it not arrive on time. TSA-compliant, it will also tell you if the TSA opened your bag during your trip.
