How payment tokenization works
PAN (real card number)
→
Token (format-preserving substitute)
→
Merchant / Wallet
Tokens are generated by the Token Service Provider (TSP) and stored in place of the real PAN. They have the same length and pass Luhn, but map to the actual PAN only within the TSP vault. The domain restriction (merchant, device, channel) ensures tokens cannot be reused elsewhere.
