This video tip applies to any cards like this that use NFC, e.g. keycards from hotels, amusement parks, and wristbands from certain events. Just try scanning the card with your phone to see if it's NFC-based. If it is, you'll be able to use apps like Automate on Android to trigger apps, sound profiles, home automation tasks, and much more!
It certainly beats sticking them in the bin! Turn them into something useful & help automate your life
