How does Automatic Billing Updater work?

Typically:

• You have a recurring payment set up with a merchant(s).
• Account changes are made to your credit card account (new card number, updated expiration date due to reissue, etc.).
• You will not need to advise merchants about changed account information. The ABU provides updated account information to participating merchants on your behalf. This allows recurring transactions to continue without interruption, thereby resulting in fewer authorization declines.
