Visa Account Updater (VAU) allows you to update your debit card number and expiry date. You can do this securely at participating merchants who have your card details on their file. This service is available to you at no extra cost. If you have set up a pre-authorized payment and your respective merchant has selected to use the Visa Account Updater (VAU) service, they will receive your new card details when your information changes at ICICI Bank Canada. Please note, not all merchants participate in VAU, so it is your responsibility to ensure that your debit card information is updated at all merchants where you have pre-authorized payment set up. You must settle any dispute or liability, if any, for transactions relating to those pre-authorized payments directly with the merchant involved.
