What is Account Updater?

Account updater is the secure exchange of updated payment card details and account information, facilitated by the card brands. Whenever card credentials update for any reason, the new details flow through card brands, from card issuers and acquirers, to merchants who then vault them for future use. This reduces churn and checkout friction, because customers never have to re-enter payment information to complete a purchase.
