As you know, wireless communication modes have been widely adopted in many ways and play an important role in facilitating the use and communication of different gadgets. NFC, such as Bluetooth and WiFi, is one of the common wireless communication technologies between smart devices that uses radio waves to communicate and can be used in a variety of areas including facilitating file transfer between devices equipped with this technology, performing financial services, controlling various devices, playing games , Health, treatment, sales and more.

Definition

NFC stands for Near Field Communication, and the NFC chip uses near-field radio waves to establish wireless communication within a few centimeters between the two devices and transfer little amount of information.

History

The NFC community began operating in year 2, but the date of the use of radio waves near Field 2, and World War II, to track warplanes, although the date of the formation of NFC technology began in year 6 Charles Walton filed his first patent with the term RFID or Radio Frequency Identification, and his patent became the starting point for a standard invention, chip, and NFC tag. Here’s a look at some of the most important events in the technology’s history since 7 years.

• NFC invented by Sony and Philips in year 4

• Registering NFC as a standard by the International Organization for Standardization in year 2

• Founded by Sony, Philips and Nokia in the NFC community in the year 2

• Creating the first NFC tag and launching the first technology-powered smartphone, Nokia 2, in 2 years

• Consumers in the UK use NFC sticker for Nokia phone 2 in year 1

• Communicate between the two phones and exchange information between them via NFC for the first time in a year

• Release of N logo (NFC trademark) in year 2

• Samsung’s first NFC-powered Android handset to launch in the year

• Use NFC-tagged phones and bank cards to provide transportation and tourism services and services to students in the year;

• Use NFC to start playing and sharing audiences, URLs, and videos per year

• Introducing smart tags by Sony to change phone modes and profiles in the near future

• Samsung and Wizacart collaborate to develop mobile payment using NFC in year 2

• Developed an NFC-based identity recognition security system by IBM scientists in year 4

• Apple Pay with NFC for iPhone 6 , iPhone 6 Plus and Apple Watch (released April 6)

• Enable Android Pay for Android NFC-enabled phones in year 2

• Release of Windows 10 with NFC architecture and release of NFC World Driver for this version of Windows in year 2

• Creating a CoreNFC Framework for Reading NFC Tags in iOS 11 per year

Structure and mode of operation

As we said, NFC technology uses near-field radio waves to communicate and transmit information between the two devices, but let’s get you started with how NFC chips and NFC chips and different types of technology work more precisely. , Classify the NFC devices and the different modes of communication between them.

NFC chip

The NFC chip is an integrated circuit that is integrated with the NFC tag and allows NFC-related activities to be tagged. NFC chips of different types are not usable per se and must be equipped with an antenna to provide near field communication coverage. All NFC chips have unique IDs, read and write memory, and memory lock capabilities.

NFC sticker

The NFC tag is a component of the NFC chip and antenna that complies with the NFC protocols, and only NFC-enabled phones can read them. These tags are capable of storing information that only NFC-enabled devices can retrieve. NFC tags, meanwhile, can transfer information between two devices.

NFC tags are divided into passive and active. Passive labels, like labels, contain information that other devices can read, but they cannot read the information themselves. Active labels also look similar to passive labels, but are equipped with an onboard power supply for transmitting waves and being able to read and write information and transmit it. Both types of labels have an antenna, an integrated circuit, and a wafer (a thin piece of semiconductor material).

NFC tags are made of various materials such as adhesive paper, discs, printed circuit boards, epoxy and metal labels and some of them are very resistant.

NFC tags are generally divided into four types, which you can see in the table below:

ISO14443A: Contactless Cards Standard for Identification and Data Transfer Protocols for Communicating with These Cards (the world’s most widely using non-contact standard and is mainly uses to pay for public transport)

ISO14443B: A similar standard to ISO14443A with the ability to create continuous magnetic fields and communicate at a speed of 1 kHz

Flicka System: A non-contact intelligent communication system under RFID (NFC-like technology) used in electronic money cards

As you can see in the table, labels type 1 and 2 can both be produced with read and write memory and can be read / write only, but types 1 and 2 can only be read-only.

To transfer information to these types of labels, either a special device is use to write the information on the labels or the data is transmit to them during production.

In the video below you can see several applications of NFC tags (map and routing, calling the target audience, displaying text messages (SMS) to the target audience); displaying email, running the app, showing online video, opening a Facebook page and optimizing the website for the platform Mobile) and how to scan them with your phone.
