Why Cardinator
Offline-first storage
Every card, barcode and image lives locally on your device. Cardinator works fully offline for all core features — no connection required, ever.
Encrypted QR transfer
Move a whole cards collection to another phone in seconds with an encrypted, peer-to-peer handoff. No intermediary servers ever touch your cards.
Zero tracking
No analytics SDKs, no advertising networks, no profiling. Your behaviour inside the app is never monitored or reported to anyone.
No cloud sync
There is no backend. We hold no copy of your data and have no ability to read, restore, or leak it — because it was never ours to begin with.
Biometric lock
Optional Face ID / fingerprint locking secures access using your device's own hardware. Cardinator only ever receives a pass/fail signal.
NFC & Quick Share
Share individual cards via NFC, QR or local wireless transfer — always user-initiated, always direct device-to-device.
How it works
Add your cards
Scan a barcode or QR code with your camera, or import a photo of the card. Cardinator reads and stores it on the spot — every detail stays on your device.
Seal it shut
Switch on biometric unlock and your wallet opens for you alone. Lose the phone and your cards stay sealed behind your fingerprint or face — useless to anyone else.
Carry it anywhere
Upgrading your phone? Beam the entire collection across in a single encrypted QR handoff — no accounts, no sign-ups, no migration headaches.
