RFID is a process where radio waves are used to uniquely identify the items. It comprises of 3 elements i.e. a tag, a reader and an antenna where, the reader sends an interrogating signal to the tag via. antenna, and the tag responds with its unique information. The tags in RFID are either active or passive which means an active tag are powered and can transmit data whereas a passive tag must be powered by a separate device.
Near Field Communication (NFC) is a subset of RFID with some same properties as of RDIF including one-way communication without a direct line of sight; however, there are some major differences between the two. To begin with, NFC is actually capable of a two way communication which is used for more complex and secure interaction. Most of the mobile devices these days are NFC-enabled which means it can be used as a mobile reader device and do not require an external infrastructure for reading.
