Near-field-communication (NFC) is the better, safer way to protect brands while ensuring ease of use for accessories and consumables. With NFC, the device itself can verify the authenticity and can configure operating modes or change settings based on the type of accessory or consumable. With a standard NFC phone, a user can check the originality or trigger a reorder through a simple tap. In this presentation we will show which options exist on NFC tag and reader side, and how to implement a solution in a practical example.
