Libelium's RFID/NFC module supports both operations in a native way: RFID @ 13.56 MHz (ISO/IEC 14443-A/Mifare® protocols) and NFC (NFCIP-1), but Libelium has not implemented software functions to handle the NFC operations. The reason to that is that the most important applications of the RFID/NFC module for Wireless Sensor Networks are identifying and reading/writing cards and tags, and not interchanging big amounts of data in very short range communications. Besides, only the most advanced smartphones support NFC, so there are not many potential users yet with NFC-capable phones.
