All rights reserved.■ TagsNokia Field Force NFC shell comes with two tags, which are used to identify objects and tasks.Note: The tags may set off the Electronic Article Surveillance (EAS) alarms used, for example, fortheft-protection in shops.■ What are RFID and NFC?RFIDRFID technologies use radio waves to automatically identify individual objects. By emitting a short-range radiosignal, the RFID reader device supplies power to an otherwise inactive RFID tag, allowing the device to read thetag or write data to the tag's memory.The RFID reader is a short-range device (reading range 0-5 cm) and it converts the radio waves returned fromthe RFID tag into a format that can then be passed on to an application in the phone.To transmit data from the RFID tag to the RFID reader, Nokia Field Force NFC shell uses the radio frequency13.56 MHz, which is the most widely used globally available frequency for RFID.NFCNFC (Near Field Communication) is a short-range radio frequency technology that evolved from a combinationof contactless RFID and interconnection technologies. The NFC device allows users to read small amounts ofdata from tags, as well as to communicate with other devices, by a simple touch.
