In this paper, the authors present the design and implementation of a complete Near-Field Communication (NFC) tag system that supports high-security features. The tag design contains all hardware modules required for a practical realization, which are: analog 13.56-MHz Radio-Frequency IDentification (RFID) front-end, a digital part that includes a tiny (programmable) 8-b microcontroller, a framing logic for data transmission, a memory unit and a crypto unit. All components have been highly optimized to meet the fierce requirements of passively powered RFID devices while providing a high level of flexibility and security.
