NFC – Near Field Communication.

Contactless near field data exchange and authentication via smartphone.

What is NFC?

NFC stands for Near Field Communication. It is a technology for contactless data exchange in near field ranges and is based on high-frequency RFID technology (13.56 MHz). Many of today's smartphones support NFC and are therefore capable of simulating contactless cards for authentication. At the same time, an NFC device can work more or less like a reader and read cards and transponders itself. NFC also supports peer-to-peer communication (P2P) between two active devices. The major advantage of NFC is its extremely low energy consumption.

Applications

What is NFC used for?

NFC is suitable for the following three types of use.

Peer-to-Peer (P2P)

This is the data exchange between two devices, such as between a smartphone and a point-of-sale terminal.

Card emulation

An NFC device (a smartphone, for instance) can be used as a contactless identification method and held to an NFC-capable RFID reader for authentication.

Read/write mode

The NFC-capable device (such as a smartphone) is in an active mode and reads a passive tag (e.g. NFC paper label).

Applications

What is NFC used for?

NFC can be used in a number of applications for secure and convenient contactless authentication – and it is also gaining ground in applications for payment systems, exchanging multimedia files and in the retail segment:

Further Applications

Range

What is the range for NFC?

The transmission range of NFC will typically be 10 centimeters but varies significantly depending on the device used. Due to this short distance, in certain applications an established connection is considered consent to a transaction (e.g. for mobile payments).

Speed

How fast is NFC?

It only takes a split second for a connection to be established between two NFC-capable devices. The maximum transmission speed is 424 kbit/s. NFC is therefore ideally suited for mobile payment systems.

Mobile devices

What mobile devices support NFC?

Almost all common smartphones with Android operating systems and many consumer devices support NFC.

Difference RFID/NFC

What is the difference between RFID and NFC?

NFC is based on RFID technology for contactless data transfer. It assigns certain RFID transponder types to appropriate NFC tag types, enabling extensive standardization and compatibility when used with contactless cards. The main difference between NFC and classic RFID is the peer-to-peer connection in which two active NFC devices exchange data directly.

NFC tags

Does ELATEC offer NFC tags?

While ELATEC does not offer its own NFC tags, our NFC-capable readers can read most of the NFC tags available in the market.
