If you find luggage with a Bagtap attached to it, you should scan the Bagtap in order to find out who the owner is. To do so, you have to activate NFC in your smartphone and hold it agains your Bagtap. Immediately the profile that is stored on the Bagtap will be displayed. If your smartphone does not support NFC, you can scan the QR-Code alternatively.
