generate

generate(
customer: CustomerInfo,
passkey: string,
config: ComplianceConfig,
): CardResult

Source: index.ts:135

Generates a unique closed-loop reward card (PAN + expiry + CVV + keyId) from customer identity data.

Every call produces a different PAN even for the same customer, because a CSPRNG salt is mixed into the hash before digit generation.

⚠️ The returned cvv is SAD — do not persist it. Store keyId alongside the card record for future validation. Call redactCardResult() before saving.

Parameters

customer (CustomerInfo) — Full customer identity information
passkey (string) — Secret passkey (≥16 chars) for CVV HMAC key derivation. Must be distinct from any PAN encryption key.
config (ComplianceConfig) — Optional compliance config (pbkdf2Iterations, keyId, onEvent)

Returns

CardResult
