How does an account updater work?
Issuers report card changes to the scheme. Visa’s developer documentation describes participating issuers sending new account numbers and expiry dates to Visa Account Updater when they reissue cards, and merchants, through their acquirers, sending inquiries about the cards they keep on file and receiving updated details where available. Mastercard’s Automatic Billing Updater supplies updated card numbers and expiry dates in a similar way, and merchants can query it on demand or subscribe to updates. Besides new details, the services can report that an account was closed, which tells the merchant to stop charging that card and ask the customer for another one.
Why does it matter for approval rate?
A stored card with an old expiry date or a replaced number is declined, and retrying it does not help. As an illustrative example: a subscription business with 20,000 saved cards where 2% change each month would see about 400 renewals fail every month without updates. If the updater refreshes 60% of them before the next billing date, about 240 payments go through without the customer doing anything, and the dunning process only has to chase the rest.
What are the limits?
Coverage depends on issuer participation and differs by country. Batch updates can lag behind a reissue, so the first charge on a new card may still fail. Stripe’s documentation also notes that an automatic update can change a card’s brand, and that a card whose brand changes cannot be charged for merchant-initiated payments until the cardholder agrees again. Most merchants get account updater through their PSP or acquirer rather than registering with the schemes themselves.
Where does Omno use it?
Account updater services are provided through acquirers and PSPs, so whether they apply to a given saved card depends on the provider arrangement. Omno’s tokenization stores saved cards at the platform level for repeat payments, and the routing-decision log keeps the decline code for every attempt, so expired-card and invalid-account declines on saved cards can be tracked per provider.
