Engineered for trust
Every stamp backed by an immutable ledger.
No fragile spreadsheets or easily-forged paper cards. Kardly combines atomic database transactions, replay-proof QR tokens, and strict multi-tenant isolation.
Append-only ledger
Every earn, redeem, bonus, and reversal is recorded as an immutable ledger entry with balance reconciliation.
HMAC-signed QR tokens
Counter QR codes are cryptographically signed with idempotency keys and daily scan limits to prevent replay abuse.
Apple & Google Wallet
Customers keep their card in the browser PWA or save native passes to Apple Wallet and Google Wallet.
