A customer loyalty system assists to build and keep a customer base. The system gathers feedback from customers and enables tracking of goods and services. The customer loyalty system rids a customer of multiple loyalty cards by replacing them with one account. A customer account is associated with, for example, a customer cell phone number. A short¬ lived promotional code enables the customer to pay through a virtual wallet and to receive bonus points or rewards. A point of sale (POS) system generates a bill with a short-lived active promotional or activation code. The code identifies the currently ordered or selected goods or services at a particular establishment. The code expires after a few minutes or other relatively short time. Through, for example, a mobile Internet-enabled device, a customer redeems the short-lived code. Redemption may be done in a variety of ways, and may be done before or after payment, but before code expiration. |
