A wireless IoT device is getting more and more popular. The device may communicate with other devices without any communication infrastructure whenever these devices are sufficiently close. In view of energy consumption, this approach, i.e., infra-less communication is considerably cheaper and more efficient since energy dissipation grows with at least the square of the distance. With this "energy wise" approach, battery-less and contact-less communication nodes are becoming increasingly attractive for future pervasive computing. In this paper, we study important design considerations and technical limitations for realizing such a device, and then we propose D2ART (Direct Data Accessing from Passive RFID Tag) that not only performs as a normal passive RFID tag for identification, but also provides rich information such as multimedia to a reader with extreme low power consumption. Our fabricated D2ART IC is operational within 7-8 cm at data transmission rate of 5 Mbps by interfacing with a conventional flash memory according to the measurement and post-layout simulation results with reasonable assumptions.
