What access do additional cardholders have to my account?
The additional cardholders will need to have internet banking access. Once they have the access they can view accounts where they have been nominated as an additional cardholder. In internet banking they can:
• Log on with their own membership number
• Change their contact details
• Set up alerts, e.g. SMS balance alerts
• Access statements Overall additional cardholders can perform most functions apart from transact on the account. They also cannot open further products, apply for loans, etc. using their membership number.
