Visa Account Updater (VAU) enables a secure electronic exchange of account information updates between participating Visa card issuers and acquirers for credential-on-file merchants, which enables a more seamless payment process.
When participating issuers re-issue cards, they submit the new account number and expiration date to VAU. Issuers also provide whether an account is closed or a card holder has opt-out out. Participating merchants through their acquirers send inquiries on their credentials-on-file to VAU and are provided with updated card information, if available. This helps participating issuers retain cardholders by maintaining continuity of their payment relationships with participating merchants.
