Tokenization replaces sensitive data – such as a card PAN – with a non-sensitive token that maps back to the original value held in a secure vault. Your systems use the token for everyday operations and never store the real card number.

For compliance this is decisive: because the sensitive value lives only in a certified environment, the systems that handle tokens fall outside the most demanding PCI controls, shrinking both your risk and your audit burden.
