Smart luggage using bluetooth to lock or unlock your luggage. 1. Traditional luggage: using a lock that is secured by a mechanically set password. 2. Smart bluetooth suitcase: install the “lock / unlock app” on your smartphone. When approaching your suitcase the “lock / unlock app” will automatically unlock your suitcase; moving away from your suitcase for more than five meters will cause the “lock / unlock app” to lock it again. Providing a traditional mechanical black lock is an additional safety measure. The app will show the location of the suitcase.
