The 4D Loyalty Program module is intended for recording and rewarding customer loyalty, regardless of the point of sale at which the purchase was made. It is always possible to add a new customer, view the current balance of collected points or benefits, as well as redeem them. The 4D Loyalty Program provides users with 8 different mechanisms for data collection, point accumulation, and spending of collected reward points, regardless of whether they are defined as points, euros, or discounts. For the loyalty program to function, it is necessary for the POS registers to operate in on-line mode.
