When processing credit cards, your processor generates a token to symbolize the credit card number. This unique token is shared with eTapestry in case you're setting up an auto processing schedule. That way, the same card can be referenced and charged again without having to re-enter it each time a transaction is scheduled to process. This tokenization process allows for eTapestry to be Payment Card Industry (PCI) compliant because we do not store or allow you to access the full card number. We only store the token, last four numbers on the card, and expiration date.
