I just released a new project called TapReturn, a 3D printable NFC recovery tag designed to help lost items find their way back to their owner. The idea is simple: print the tag, install a round NFC sticker, activate it with a free TapReturn account, and attach it to your keys, backpack, luggage, or gear. If someone finds your item, they can tap the tag with their phone or scan the QR code backup to quickly contact you and send their location.
