All You Need To Know About NFC Technology
The NFC technology , more commonly called “Near Field Communication” or “Contactless”, it is how to communicate with mobile devices and smartphones objects, devices and machines in order to transmit information or authenticate.
NFC , or near field communication, enables smartphones and other devices to communicate with other devices or articles containing an NFC tag.
If you move your smartphone through the shelf of articles in a store, or passing it near a work in a local museum, or bringing the phone with a friend to share the latest games, near field technology or “contactless” allows you to pay, play, authenticate and learn with ease.
The NFC has two clear divisions of practical application:
- Payments through smartphones
- Public transport
- Payment gateways in general, …
- Other non-paid applications
- Brand protection
- Access controls
- Interaction with the client

How Does NFC Technology Work?
Transmission frequency and speed: like RFID, NFC works in the 13.56 MHz radio frequency spectrum, but with less than 15 mA of power to be able to communicate data over distances of less than 20 cm.
NFC tags typically store between 96 and 512 bytes of data, and data transfer uses a speed of 106Kb / s, 212Kb / s, 424kb / s, or 848kb / s – enough to move small packets of information virtually instantaneously. .
Regulations And Protocols
NFC interfaces are defined and standardized under ISO and ECMA standards. The ISO / IEC 18092 and ECMA-340 define communication modes for the NFC interface and its Protocol (NFCIP), an active and passive communication mode is selected and the relevant modulation systems, encodings, transfer rates, the format of frame, collision control parameters, transport protocol and more.
ISO / IEC 21481 and ECMA-352 define NFCIP-2, which specifies communication modes to minimize interference with other devices for contactless cards.

NFC helps us to interconnect products with the network, and there are many applications that can be developed with it. Here are some of the most common today:
- Payment by mobile phone : It is one of the most widespread applications . With a mobile and a dataphone equipped with it, payments can be made safely, which is very useful due to how indispensable these devices have become in our daily lives.
- Identification : Another of the most common uses of it is to use it as an access control mode in places / events where identification is required.
- Product authentication: The NFC facilitates the identification of the authenticity of the products, avoiding fraud or counterfeits and being able to connect them with specific machines so that they recognize the authenticity of the product.
- Campaigns / Promotions: This technology allows the creation of “smart” campaigns, where users can access all the information simply by placing their mobile device near the NFC tag.
- Consumer loyalty: NFC helps in communication between companies and customers, facilitating the creation of personalized offers and promotions.
- Automation of actions and instant synchronization between devices.
