The suitcase features our innovative new Smartlock technology. Simply download the app, pair your suitcase and you're ready to go. With our easy-to-use, password-protected app, you can lock and unlock your suitcase with a tap of a button. Or why not switch to automatic mode? Your suitcase will automatically unlock itself within Bluetooth range, and lock itself when it moves out of range. You can also enable notifications on your mobile, which will notify you when your suitcase enters or leaves your location. The lock is supplied with an emergency key in case your mobile device fails, and the lock is TSA-approved too for easy clearance to the United States!
