Summary: Account updater pushes reissued card details to merchants automatically, addressing the largest cause of failed subscription payments.

**Card account updater is a service through which card networks push updated card details to enrolled merchants when a card is reissued.** An expiring card, a replaced lost card, a new number after fraud — all update automatically, before a payment ever fails.

## Summary

It addresses the largest single cause of failed subscription payments. Updates happen before the failure, not after. Coverage is strong on Visa and Mastercard, weaker elsewhere. It complements dunning rather than replacing it.

## Why it is the highest-leverage fix

Expired and reissued cards together account for roughly half to two-thirds of failed subscription payments. Neither is a customer decision, and neither can be fixed by retrying — the stored credential is simply wrong.

**Where each tool applies**

| Failure cause | Account updater | Dunning |
| --- | --- | --- |
| Expired card | Fixes it before failure | Asks the customer to fix it |
| Card reissued | Fixes it before failure | Asks the customer to fix it |
| Insufficient funds | No effect | The right tool |
| Bank declined | No effect | Sometimes helps |
| Card cancelled | No effect | Rarely recovers |

The two are complementary, not alternatives. Updater removes the failures it can prevent; [dunning](https://www.paydude.io/resources/what-is-dunning) handles the ones it cannot.

## Its limits

- **Not every issuer participates.** Coverage varies by bank and by country.
- **Amex and Discover coverage is weaker** than Visa and Mastercard.
- **Updates are not instantaneous.** Batches run periodically, so a card can still fail in the gap.
- **It does nothing for a genuinely cancelled card.**

> **Network tokens are the better version:** A [network token](https://www.paydude.io/resources/what-is-tokenization) does not need updating at all — it stays valid when the underlying card changes. If you are choosing where to invest, tokens solve this problem permanently while account updater patches it. Updater remains useful for cards already stored.

## Is it worth enabling?

Almost always. The cost is cents per card checked; the return is a subscription that would otherwise have lapsed. On any product where customers stay more than a year — long enough for cards to expire — it pays for itself repeatedly.

**Fewer failed payments, lower fees on the rest** Published rates that improve automatically with volume. — [See pricing](https://www.paydude.io/pricing)

## Frequently asked questions

### How much does account updater cost?

Usually a few cents per card checked, or it is bundled into the platform. Against a recovered subscription worth many months of revenue, the arithmetic is rarely close.

### Does it work for every card?

No. Coverage is strongest for Visa and Mastercard, weaker for Amex and Discover, and depends on the issuing bank participating. Expect meaningful but not complete coverage — it reduces failures rather than eliminating them.

### What is the difference between account updater and network tokens?

Account updater pushes you a new card number periodically. A network token is a credential that never changes even when the underlying card does, so there is nothing to update. Tokens are the better long-term answer; updater works with cards you already store.

### Do I need it if I already have dunning?

Yes. They solve different problems. Dunning handles the message and the retry; account updater fixes the stale credential that caused the failure. Expired and reissued cards are the largest failure category, and dunning alone cannot fix them.
