====== Account Updater ======

“Account Updater” refers to Secure Tokens saved on %CompanyName’s system, which have had their Cardholder details updated electronically via “Visa Account Updater” (VAU), and “Mastercard Automatic Billing Updater” (ABU) respectively. This is a process which helps to ensure a smooth automatic billing cycle by minimising payment disruptions due to account changes.

Example Use Case:

  * Customers Secure Token is saved to the gateway.
  * A monthly subscription is created for the customer.
  * Time passes, and eventually the card expires.
  * %CompanyName sends a request to Mastercard or Visa asking for the new card details.
  * Visa/Mastercard sends the updated card details back to %CompanyName.
  * The customers card (Secure Token) is updated with new info.
  * Next months subscription won’t be affected because we now have the correct card details stored for the customer.

===== Account Updater Background Notification =====

Account Updater Background Notification (AUBN) is a tool that enables merchants to receive the updated card details.

The merchants will receive the information below:

  * New expiry date.
  * New card number, if it has been changed.

**Secure Token Custom Fields (SCCFs)**

At the moment, Secure Token custom fields are only useful with Account Updater Background Notifications. Because of this, SCCFs are only editable/viewable when Account Updater Background Notifications are Enabled.

**SCCFs Limit**

  * Each terminal can have a maximum of 3 SCCFs.
  * These fields are useful for any custom data the merchant wants to record about the customer for example: accounting software related data.

**To create SCCFs on the %SelfCare System**

Once the Secure Token Custom Fields are set, they will be displayed when adding or editing a Secure Token in %SelfCare system.
