The GhDual card will work based on a customer's preference. Customers, who want to withdraw money or spend off the e-zwich side of the card, will need an e-zwich only terminal or a hybrid terminal. It will also require fingerprint authentication.

Similarly, if the same customer wants to spend off their bank account, they will need a gh-link compliant terminal. The standard authentication of transactions for gh-link will apply. However, where there are Hybrid terminals (terminals with both e-zwich & gh-link applications), that can be used to perform both e-zwich & gh-link transactions at the same time.
