Traditional plastic punch cards and loyalty key fobs are rapidly becoming obsolete. They are frequently lost, forgotten at home, and provide zero customer data or direct communication channels.

Digital loyalty cards in Apple Wallet and Google Wallet replace physical cards with an interactive, cloud-connected mobile asset that updates in real time upon every transaction.
