Near Field Communication (NFC)

NFC stands for Near Field Communication. It is a wireless communication protocol, based on high frequency RFID technology (13.56 MHz).


What applications use NFC?

NFC covers a large number of applications like payment or swap of multimedia files, and new uses are constantly added. It can also be integrated in business cards, deployed in museums, educational facilities, retail and many other environments.

It supports three different operating modes:

Peer-to-Peer (P2P)

For data exchange between two devices.

Card emulation

A smartphone can be used as a contactless identification card.

Read/write mode

In which an active device such as a smartphone can read out pre-saved information in a passive one (e.g., NFC paper label).

What is the transmission range of NFC?

The communication range of NFC is limited to about 10 centimeters (four inches) and compared to other contactless technologies it has pretty low power consumption.

How fast is NFC?

Just a fraction of a second is needed for a connection establishment between two NFC enabled devices with a transmission speed of 424 kbit/s. This advantage makes this technology very suitable for mobile payments.

What devices support NFC?

NFC is supported by almost all current Android smart phones.

What is the difference between RFID and NFC?

NFC is based on RFID technology for contactless data transfer. When used with contactless cards, NFC makes the process extremely straightforward by enabling an NFC tag type to be assigned to certain RFID transponder types, which are compatible with one another. The main difference between it and standard RFID is the peer-to-peer connection that lets NFC devices communicate directly.

What actually is NFC?

NFC, which stands for Near Field Communication, is a contactless technology that nowadays is mainly found in many cell phones (i.e., smartphones). It allows a cell phone to act in the same way as a contactless card. An NFC device can also work more or less like a reader and read cards and transponders itself. However, NFC is an HF technology and will not detect any LF transponders.

Which ELATEC products are NFC-compatible?

All TWN4 scanners with an HF interface support NFC. In terms of other providers, most commercially available cell phones are fitted with NFC, as are many consumer devices.

What is the range and what factors does it depend on?

The range will typically be up to 10 cm and will vary significantly depending on the device being used. Because this distance is short, it means that the establishing of a connection can be treated as consent to a transaction.

What is NFC used for?

  • User identification
  • Access control and time tracking
  • Bluetooth/WiFi authentication (connection handover)
  • Internet of Things (IoT)
  • Smart homes
  • Payments
  • Public transport tickets
  • The “Fourth Industrial Revolution”

    What purposes can ELATEC’s NFC tags be used for?

    ELATEC does not supply any NFC tags itself. However, our readers can read most commercially available NFC tags.
