This is the most widely used application of ThermoRewrite in Japan. Points are added with each purchase, and the total points are displayed on a customer's card. Not only the customer's points but also messages for the customer, such as the event schedule and advertisements, can be printed on the card. Rewritable cards can provide up-to-date information to customers at every stage of a sale.

Since the rewritable card provides many attractive features to customers, it will be a key tool in CRM and database marketing.
