When a customer saves their card, Visa/Mastercard/Amex replace the real 16-digit PAN with a network-issued token (a cryptographically unique 16-digit number that only the card network can map back to the real card). This token lives in your system instead of the real PAN.
Benefit
Real-World Impact (averaged across $50M–$1B+ merchants)
How You Get Paid
+5–15% higher authorization rates
Tokens never expire and are updated automatically when the card is re-issued, lost, or renewed. No more “card expired” declines.
Direct revenue lift
Every extra auth = sold product
60–80% fewer false fraud declines
Issuers trust tokens 3–5× more than raw PANs → much lower decline rates on legitimate recurring or card-on-file purchases.
Fewer angry customers + higher LTV
Automatic Account Updater on steroids
Card numbers update in real time (new expiry, new card after breach, etc.) without you running batch jobs.
Zero engineering time, zero failed recurring payments
PCI scope shrinks dramatically
You never touch the real PAN after the first transaction → easier (or zero) SAQ-D compliance headaches.
