A PayID is an easy way to communicate your account details to other people, by providing your mobile number. Once it’s set up, when someone owes you money, simply ask them to pay you using your PayID. Create your unique PayID in just a few easy steps by logging into NAB Internet Banking. When your PayID is registered, your details (including your name) will be available to people who use the service and enter your mobile phone PayID. Follow the same set up steps to link a PayID to a Westpac business account. URL
