Add a second cardholder

You can add a second cardholder in store or in internet banking:

  • Click 'Apply now' in the menu.
  • Select 'Add a cardholder' under the credit cards heading.
  • Select the credit card you'd like to add another card holder to.
  • Enter the second cardholder's details and submit.
