The ADIO2 contains a so called NFC (Near Field Communications) chip. The chip contains information that identifies the board, its MAC address and IP address as well as a user supplied description. The information is read by placing an NFC equipped Android phone in the vicinity of the attached NFC antenna. Once the information is read, the user may modify the description and transfer it back to the ADIO2 board.
Both reading and writing information may be performed without powering the ADIO2 board.
