A GhDual Card is a two in one payment card, that has both the e-zwich & gh-link applications. It therefore can be used either as e-zwich or gh-link or both as desired. Depending on the request of a customer, an issuing bank can activate any of the functionalities that serve a customer's purpose.  The card has been designed to give cardholders access to both funds on their e-zwich cards and in their bank accounts at the same time.
