An additional cardholder allows a nominated person to use your existing credit card account, with their transactions appearing on your primary monthly statement. This feature is often used to help family members manage shared expenses while keeping the primary account holder responsible for the total balance and repayments.

When you request an additional card, the bank conducts a verification process to ensure the new cardholder meets the minimum age and residency requirements. Because the primary account holder remains liable for all spending on both cards, it is helpful to ensure the person you nominate understands the credit limits and terms of your account.

Troubleshooting Common Issues

MFA and Login Issues: If you cannot complete the request due to an MFA error, verify that your mobile device is receiving security codes correctly. If codes are delayed, try restarting your device or updating your contact details in the 'Profile' section of your account before trying again.

Browser or App Errors: When the application page fails to load or shows a technical error, clear your browser cache or force-close and restart the mobile app. Often, these errors are due to temporary network congestion, and retrying the request after a short interval usually resolves the issue.

Locked Account Access: If your ability to add a cardholder is restricted, this could be because your account has a temporary security flag or your credit card account type does not support additional cardholders. Contact the bank’s customer service line to confirm your account features and verify your identity to clear any administrative holds.

Pro-Tip: Before adding an additional cardholder, set a specific individual spending limit on their card if your account type allows it. This helps you maintain control over your total balance while still providing the flexibility the other person needs for their purchases.

Frequently Asked Questions

Q: Why was my application for an additional cardholder declined?
Applications may be declined if the nominee does not meet the minimum age or residency requirements set by the bank. The bank also assesses the primary account’s current standing; if there are outstanding arrears or if the credit limit has already been reached, the request might be held or rejected. You should check your current account status and ensure the nominee meets all criteria before submitting a new application.

Q: Can I cancel the additional cardholder at any time?
Yes, you can remove an additional cardholder whenever you choose. To do this, use the 'Manage cards' section in your online banking to cancel their specific card. The primary account holder must initiate this change, as the system stops all future transactions on that card from the moment it is canceled. If you have any concerns about unauthorized transactions, contact the bank immediately after processing the cancellation.
