What Is NFC Mobile Technology?

With the arrival of the pandemic, payments by phone and by watch have become more popular, but do you know how this type of communication works, which works without the need to link to another device? All this is thanks to NFC mobile technology.

Most mobile phones come with this built-in technology, commonly known as NFC mobile technology. It is a type of wireless communication based on approximation. However, there are specific characteristics that differentiate it from regular communications, such as Bluetooth or Wi-Fi, and in this article, we are going to show you what NFC is, how this type of communication works, and much more so that you can, you can answer any question you have about NFC mobile technology.

But first of all, consider giving your phone a second life. Look at this list of second-hand phones. You will be able to choose from dozens and dozens of modern phones. In this way, you will not only be giving your portfolio a break, but you will also be helping to reduce the environmental impact of technology. And above all, remember: you don’t need the latest model to have a good mobile!

What is the NFC of my mobile?

You have probably heard about NFC mobile technology communication and the things that can be done with it, but what is the NFC of your mobile? NFC stands for near-field communication. Its function, as its name suggests, is to communicate wirelessly with other devices near it. Unlike Wi-Fi or Bluetooth, NFC interaction is limited to extremely short ranges, about a range of about 10 centimeters.

NFC mobile technology has evolved from radio frequency communication (RFID). Despite its concise range, it is used in various fields and is being implemented more often, whether it is to pass the train toll or pay for the food you just put in your body.

Its short range makes the person feel more secure with this type of security, which is one reason why NFC mobile technology has taken off as a fast alternative to credit cards.

How does the NFC of my mobile work?

Unlike a Bluetooth connection, NFC mobile technology doesn’t require you to pair anything or locate any device to transfer data manually. With just proximity, NFC automatically activates to send data from one device to another. When two devices get close enough, they instantly communicate and perform their function.

As we mentioned before, NFC is the evolution of RFID communication. They both work on the principle of inductive coupling when in close range. This implies that the reader device generates a magnetic field by passing an electrical current through a coil. Once this field is created, when approached by an NFC tag with its wave, the field induces an electrical current inside the tag without wires or physical contact.

Once all these preparations are done, the data stored on the tag is wirelessly transmitted to the reader.

The main difference between NFC and RFID lies in their transmission ranges: the latter is usually used over long distances. An example of RFID communication is the labels that are generally placed on the windshield to be able to pay the toll remotely (approximately, it has a range of 15 meters).

Another feature of NFC is that it can be used as both a reader and a tag; It has the bidirectional capability and can both send and receive data. 

In which services can NFC be used?

If you have a mobile phone with NFC, you can use it in various situations. Unlike Bluetooth, NFC doesn’t require devices to be paired or anything like that to transfer data. The NFC connection is automatically activated when another NFC device enters the range of 10 cm. When they communicate, the devices connect and send prompts to the user. Next, we are going to list some of the most common situations:

  • Mobile payments. More and more supermarkets and service centers include the possibility of paying with the NFC of your mobile. By placing your mobile (after unlocking it and enabling your card) near the label, the payment will be charged, and you will receive a message with transaction information.
  • Share data between Android devices. Android Beam allows devices with this operating system to share content thanks to Android technology. When two NFC mobile technology enabled devices are brought together, they sync up and can send data to each other.
  • Passive NFC chips or stickers. They do not require power and can be programmed with applications such as Tasker to perform specific tasks. If you are a handyman, you can program one of these chips so that, for example, if you pass you are mobile nearby, you deactivate all notifications.
