RFID vs NFC

 RFID vs NFC

Difference Between RFID and NFC is that RFID is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person. While NFC stands for near field communication. It is a communication protocol that enables two electronic devices in close proximity to interact with each other. One of the two devices is portable device like smartphone.

 

What’s RFID ?

RFID (radio frequency identification) is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person. Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.

What’s NFC ?

NFC stands for near field communication. It is a communication protocol that enables two electronic devices in close proximity to interact with each other. One of the two devices is portable device like smartphone. One device transmits the signal while other receives the signal. Waves involved in data transmission are radio waves. It provides wireless connection between two devices only within radius of 4cm. It enables these two electronic devices to send and receive information.NFC does not cost anything as it does not require 3G, 4G or Wi-Fi.

NFC is used for sharing images, video clips, files, apps, for sending directions or sending contact information. NFC has made mobile payment possible through contactless payment systems. NFC enabled devices act as keycards.
