MIFARE products are used for more than 40 different applications. One of these is loyalty and micropayment.
Choosing a MIFARE chip for a smart loyalty program enables design freedom and greater customization, since the contactless technology can be implemented in more than just cards. MIFARE chips can be designed into a thin sticker that can be affixed to the back of a phone (or a traditional wallet or card case), and used at pay stations or used in form of a key chain or card. The app shows how easily a mobile device can interact with a loyalty card, displaying the balance offering special deals, linking to a webshop etc.
