NFC is everywhere these days. You’ve probably seen it in your phone settings or heard it in a setting.

The age of internet and technology is growing at a tremendous rate. With the 5G network and emerging support by 2020, all people are ready to enter the speed and productivity phase. While all these improvements are quite interesting, many people ask “What is NFC?” she asks. If you are researching the same thing, here is everything you need to know about NFC…

What is Near Field Communication (NFC)?

NFC Near Field Communication

Near Field Communication (NFC) stands for Near Field Communication and is a technology that has been growing for many years. It is a standard for devices to wirelessly communicate with each other at very close range. It is an essential tool that helps users to exchange data from their smartphone devices.

While the use of NFC for things like contactless payments has increased steadily, it has exploded earlier this year due to the coronavirus outbreak. Read More

NFC is a subset of another technology called RFID, so let’s take a look at this before we go back to NFC.

What is RFID?

Radio frequency identification or RFID is a general term for technologies that use radio waves from a reader to track certain tags. All of these tags contain an antenna and a small chip and can come in many shapes and sizes. Read More

Highway toll payment devices and plastic items on clothing and other expensive items in stores are some common examples of RFID tags.

If you have seen these large devices on both sides of a store entrance, these are great RFID readers, They constantly benefit from radio waves and expect a response. What if there is still a label on the item you purchased while trying to leave a store? (Most RFID tags do not have power, so when the antenna inside the tag receives radio waves from the reader, it generates a small amount of electricity. This electricity activates the chip inside the tag and sends a signal to the reader with the information stored in the chip.) In this case, the reader receives a signal back from the tag on the product you bought. and the alarm sounds.

RFID and NFC Relationship

NFC is a newer, high frequency version of RFID and also includes both tags and readers. The higher frequency of NFC means that while it can transmit data much faster than RFID, it only operates from a distance of about 4 cm / 1.6 inches or less. Meanwhile, RFID works from a distance of up to 12 meters.

NFC technology sets up a short-range network to exchange data using electromagnetic radio fields. NFC tags can be both read and written; They contain between 96 and 4,096 bytes of storage, depending on the tag type. This requires at least one transmitter device and the other to receive the signal – usually a telephone is used as the signal receiver. There are two main features for NFC technology: ISO / IEC 14443 and ISO / IEC 18000-3. The first identifies ID cards used to store information such as those found in NFC tags; the second indicates RFID communication used by NFC devices.

There are many use cases for NFC, but here are some of the most common ones you’ll see:

Contactless payments: Many new credit and debit cards have an NFC tag so you can hold your card directly above a payment terminal rather than swipe or insert it. Credit and debit cards with contactless payment features have a special symbol on them. Most modern phones contain an NFC chip that can act as both an NFC reader / writer and a tag. Paired with a mobile payment app like Google Pay, Apple Pay and Samsung Pay, this chip means you may no longer need to pull out your wallet. Instead, your phone can act as a virtual NFC tag for your credit or debit card, even if the card in question doesn’t have a real NFC tag inside.

Where Is NFC Used?

NFC tags, for example, stickers contain small microchips with little antennas which can store a small amount of information for transfer to another NFC device, such as a mobile phone. An NFC Tag itself consists of three basic components: an NFC chip, an antenna, and something to keep it together.

  1. Interaction with products: Traditionally, RFID is used in warehouses and shops to track inventory. However, when a product leaves the store, the RFID tag is disabled. Many products now include NFC tags for additional interactivity after leaving the store.
  2. Data transfer: Unlike RFID, which is typically one-way communication between a reader and a tag, NFC allows two-way communication. Some phones can use NFC to transfer data such as contacts or photos if you touch each other between two devices.
  3. Machine Surveillance: For companies whose work involves the use of various machines and tools with the required control and usage history. NFC chips can be built into each machine or tool. With the smartphone, the user can quickly record the action that has taken place. Each vehicle has its own usage history, which can lead us to better control production costs.
  4. Smart Homes: NFC chips inside homes can be installed in a variety of locations and programmed to facilitate many home settings. With a short scan of the mobile device and the chip, it opens a mobile application that allows temperature control, activation of some devices, daytime mode dynamics, light control and more. Top panels, garage doors, etc. Allows you to open and close.

Smart home technology

Smart home technology which may also be termed Home automation is the use of devices in the home that connect via a network, most commonly a home network or the internet.
