Card Updater

Card updater services solve one of the most common causes of subscription payment failures: outdated card information. When a customer's credit or debit card is reissued — whether due to expiration, loss, fraud, or the bank issuing a chip-enabled replacement — the stored card number and/or expiration date become invalid. Without an update, the next recurring charge will fail.

The major card networks operate their own updater services. Visa Account Updater (VAU) and Mastercard Automatic Billing Updater (ABU) allow merchants to submit their stored card tokens for updates. The network checks whether the card has been reissued and returns the new details if available. American Express has a similar program. These services run on a batch schedule — typically daily or weekly — and are facilitated through the payment processor.

Card updater services have significant limitations. Not all cards are enrolled — participation depends on the issuing bank opting in. Coverage varies by country and bank. The updates are not instantaneous — there can be a lag of days to weeks between a card being reissued and the update being available. And the services cannot help with all failure types — if a card is closed entirely (not reissued), there is no new number to provide.

Despite these limitations, card updaters are remarkably effective. Studies by payment processors show that automatic card updates can prevent 10-25% of payment failures that would otherwise occur. For subscription businesses with large customer bases, this translates to meaningful revenue preservation.

LostChurn integrates with card updater services through your payment processor, ensuring stored cards are kept current. The platform also monitors card expiration dates proactively, triggering customer outreach before the card expires rather than waiting for a failure. This combination of automatic updates and proactive communication provides the strongest defense against card-related payment failures.
