Account Updater is a service offered by the card schemes that allows you to update the details of tokenized cards. Account Updater should be used for Stored Credentials (e.g. recurring, subscription-based billing model). This will ensure that the tokenized credit card details are up to date at all time. For example, when a customer’s card expires you would receive a rejection due to the wrong expiry date and need to contact the customer to request the new expiry date to be able to continue billing. With the Account Updater, such disruptions to the billing cycle will be prevented; card details can be updated without having to contact the customer.

The account updater service provides updates on the following cases:  

  • Expired Card
  • Change in Card Number/PAN
  • Cancelled, Lost or Stolen Card
  • Cancelled authorization

We can enable Account Updater service for Credit and Debit cards of both Visa and MasterCard. This can be done in two different ways:

  • Subscribed updates on Tokenization ServiceAfter you have integrated the usage of the Worldline Tokenization Service, it will become possible to subscribe to the Account Updater. The Account Updater will regularly look for tokens that require updates based on predefined criteria and send update requests to the card schemes after which we update the tokens where necessary without any additional actions required by you.
  • Encrypted Batch File with transaction Details: If you are not using our Tokenization Service you can choose to make use of our Batch File solution. This solution requires you to capture the card details on your end and submit the details you like to be updated in a encrypted Batch File. We will then include these transactions in the request to the schemes. Once the response has been provided you will receive the updated records, including the reason for change and you can use these details to update your own records.

Key Benefits

  • Choose between a fully automated process and a process where you have full control
