The NFCStack Evaluation application demonstrates the functionality of the NFC stack, which handles the higher layers of all three NFC operating modes after the anti-collision process. It has been developed based on the NFC Controller Interface (NCI) protocol from the NFC Forum to communicate with the NFC Controller to enable/disable the NFC operating modes. There are four tag platforms types supported, including Type 2, Type 3, Type 4A/B, and Type 5.
