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

If you love passport stamps, travel, geography, or collectibles, StampCats gives you a modern way to record and display your journeys. Mail your cat to friends abroad for a stamp or bring it with you on your own travels. Each NFC tag is unique and tied to a single digital passport, ensuring authenticity.
