Near Field Communication (NFC) technology is a form of wireless communication that allows two devices to communicate when they are close to each other, usually within a few centimeters of each other.

NFC is a short-range, low-power communication technology that allows you to exchange information between devices without the need for wires or internet connection. This technology works by means of electromagnetic waves, which allow devices to communicate using radio signals.

A common example of using NFC technology is for mobile payments, where a mobile device (such as a cell phone) with NFC technology can be used to make payments at stores that accept NFC payment. The user only needs to bring the cell phone close to the card machine for the transaction to be carried out.

In addition, NFC technology can also be used to Share information across devices, such as photos, videos, contacts, and music files . For example, a user can share a song with another user who is nearby, simply by bringing the two devices closer together.

Some examples of routine habits in which we use NFC technology are:

Mobile Payments: One of the most popular ways to use NFC is in mobile payments. With an NFC-enabled mobile device, such as a smartphone or smartwatch, it is possible to pay in stores, restaurants and other establishments without needing cash or credit cards. Enough bring the device closer to the NFC reader and confirm the payment on the device's screen.

Public Transport : Many public transport systems around the world have adopted NFC technology to allow passengers to pay for transport fares more easily. Passengers can load their transport card with credit and then simply touch the card to an NFC reader when entering and exiting the transport.

Access to buildings and events: NFC technology is also used to control access to buildings and events. With an NFC-enabled access card, users can touch the card to an NFC reader to unlock doors or gain access to an event. This can be particularly useful at large events with many attendees, as it streamlines the entry process.

File sharing: NFC is also used to share files between devices such as smartphones and tablets. Users can simply touch one device to another to transfer files such as photos, videos or documents. This is particularly useful for sharing files between friends or co-workers.

Smart Device Control: With NFC-enabled smart devices such as door locks, thermostats, or lighting, users can control the devices simply by touching a device to an NFC reader. This is particularly useful for automating household or office tasks and can save you time and effort.

NFC technology has been widely adopted in many areas of our daily lives, from mobile payments to public transport, file sharing and smart device control. As more devices and systems adopt NFC technology, it's likely that the list of routine uses for the technology will continue to grow.

History of NFC technology

NFC technology has become more and more popular in recent years, being widely used in mobile payments, data sharing and other applications. But did you know that the history of the NFC goes back over two decades? In this blog, we're going to tell the story of NFC and share some curiosities about its creation.

NFC technology, which stands for Near Field Communication, was developed by Sony and by NXP Semiconductors (formerly Philips Semiconductors) in 2002. However, its origins can be traced back to the 1980s, when Sony began researching near-field communication.

Sony's initial research focused on a technology called FeliCa, which used radio frequencies for communication . However, the company soon realized that this technology had limitations, such as the need for large antennas and interference from other electronic devices.

It was then that Sony teamed up with Philips Semiconductors to develop NFC technology. The goal was to create a short-range communication technology that was more efficient and secure than existing technologies.

In 2002, NFC was introduced to the world for the first time at Cebit , Europe's largest technology fair . Since then, the technology has been improved and adopted around the world.

Facts about the NFC

  • NFC is an evolution of RFID (Radio Frequency Identification) technology, which is used in product and animal identification tags;
  • The creator of NFC, NXP Semiconductors, is also responsible for the development of the MIFARE chip, which is widely used in ticketing and access control systems;
  • NFC has a very short range of just a few centimeters, which makes it more secure and reliable than other wireless technologies;
  • NFC is a two-way communication technology, which means it can be used for both sending and receiving data;
  • NFC is an open source technology, which means that any person or company can develop NFC-enabled apps and devices;

The history of NFC is fascinating and shows how the technology has evolved over time. From its inception in the 1980s to its widespread adoption today, NFC has become increasingly important in our lives. With its many benefits and its reliability, it's easy to see why NFC technology is so popular and continues to evolve.
