Near-Field Communication (NFC) and Radio Frequency Identification (RFI

1.	Near-Field Communication (NFC) and Radio Frequency Identification (RFID) are two technologies that contain data.a. Describe two similarities between NFC and RFID?b. What is the difference between NFC and RFID?
Answer» a. Both use RFID technology, Both process data or information from another NFC or RFID tag b. Range – NFC requires devices to touch or be in very close range (<10 cm) RFID requires tag (passive or active), antenna and RFID reader NFC requires smart tags/chips in both devices RFID is one-way communication – data flows from tag to reader NFC can be set up for one or two-way communication (NFC device such as a smartphone functions both as a reader and a tag or transmitter) - both must be NFC enabled.

Answer»

a. Both use RFID technology,

Both process data or information from another NFC or RFID tag

b. Range – NFC requires devices to touch or be in very close range (<10 cm)

RFID requires tag (passive or active), antenna and RFID reader

NFC requires smart tags/chips in both devices

RFID is one-way communication – data flows from tag to reader

NFC can be set up for one or two-way communication (NFC device such as a smartphone functions both as a reader and a tag or transmitter) - both must be NFC enabled.
