StampCats NFC Passport

StampCats - Stamp Your Journey With a Cat

NOTE: This app requires a StampCats NFC collectible to function.

Collect Stamps From Around the World

Tap your phone on any StampCats NFC tag (a physical collectible purchased separately) to earn stamps in your cat’s virtual passport. Each stamp is cryptographically verified using unclonable NTAG 424 DNA chips and iOS’s spoof-resistant Core Location, proving you’re both the owner of the tag and physically at the location you claim to be.

• Earn stamps by visiting countries and special locations • View your stamp collection in a beautifully designed virtual passport • Track your adventures on an interactive world map • Download a CSV file of your stamp history
