Card-linked offers provide a seamless method to enhance customer retention by integrating rewards directly with customers' payment cards, reducing friction at checkout and increasing engagement both online and offline. This approach addresses common issues with traditional loyalty programs, such as customer drop-off due to inconvenient steps like remembering loyalty cards or using specific codes. By enabling automatic rewards application and real-time interaction, card-linking helps businesses build stronger relationships with customers, as evidenced by notable increases in transaction values for companies like intu and Goloyal. Furthermore, card-linking provides granular data that allows retailers to personalize offers, thereby improving the shopping experience and fostering long-term loyalty.
