LINX – a card linked loyalty program allowing consumers to join a merchant loyalty program by linking their credit card to the merchants credit card terminal. In doing so, customers automatically earn rewards, points, or cashback on qualifying purchases without needing a separate loyalty card, mobile app or entering a phone number. The LINX program tracks their spending through the linked card, and automatically facilitates reward redemption. This seamless integration simplifies the loyalty process, enhances convenience, and encourages repeat business by eliminating the need for multiple cards.
