RFID V/S NFC
By : Priyanka | November 7, 2019
NFC technology emerged from RFID technology, but in comparison with RFID, there are some differences.
So, what is the difference between them? We will guide you in understanding what NFC technology is, what the RFID technology is, and how they differ.
What is RFID?
Radio Frequency Identification (RFID) is an automatic identification technology that is non-contact. It automatically identifies target items and by means of radio frequency signals acquires appropriate information.
It can operate without manual interference in different hostile settings. RFID technology can simultaneously recognize high-speed moving items and various tags that can be operated quickly and conveniently.
What is NFC?
NFC Technology is derived from the “contactless radio frequency identification” (RFID) and interconnection technology between wireless devices, just like RFID. NFC information is also transmitted by electromagnetic induction coupling in the radio frequency part of the spectrum, but there is still a big difference between the two.
First of all, NFC is a wireless connection technology that provides easy, secure and fast communication. Its transmission range is smaller than that of RFID.
Secondly, NFC is compatible with the existing contactless smart card technology and has become a formal standard supported by more and more major manufacturers.
Thirdly, NFC is also a close-range connection protocol, which provides easy, safe, fast and automatic communication between various devices.
Compared with other connection modes in the wireless world, NFC is a close private communication mode.
The difference between NFC and RFID Technology:
1. Distance: The working distance of NFC is 0-10. Because RFID has different frequencies, it’s working distance varies from several centimeters to tens of meters.
2. Frequency: The working frequency of NFC is 13.56MHz, while the working frequency of RFID is low frequency, high frequency (13.56 MHz) and ultra-high frequency.
3. Working mode: NFC supports both read-write mode and card mode. In RFID, card reader and contactless cards are two independent entities, which can not be switched.
4. Application areas: RFID is more used in production, logistics, tracking, and asset management, while NFC works in access control, bus card, mobile payment, and other fields.
