What is NFC? – Learn more about Near Field Communication

NFC stands for Near Field Communication. It is an amazing technology that we use for two-way communication. The two-way communication takes place between a phone and an NFC tag. Such communication will be possible only when a phone will be brought close to an NFC tag (within 10 cm of the NFC tag).

In other words, we can say that this NFC technology is able to establish a short-range network in order to successfully exchange data using electromagnetic radio fields. Such tags can be easily read and written according to the requirements. Generally, NFC tags contain from 96 to 4096 bytes of storage. The storage capacity generally depends on the type of the NFC tag. In order to make data exchange possible, there should be at least one transmitting device and one signal receiving device. Even a phone can be used easily as a signal receiver.

Specifications for NFC technology

There are two major specifications for the NFC technology such as ISO/IEC 18000-3 and ISO/IEC 14443. Here, the first specification conveys the RFID communication used by any NFC device and the second specification says about the ID cards that are being used to store the required information.

How do NFC work and the working logic of NFC chips?

Just like the ways Wi-FI and Bluetooth work, NFC also works in the same way. In other words, we can say that just like any other wireless signal work the way, NFC also follows the same way. Its working principle is sending information over radio waves. It is actually a standard for better wireless data transactions.

In order to make Neal Field Communication possible, the associated devices must have some standards in order to make the communication successful. The NFC technology is nothing but the older RFID- Radio Frequency Identification ideas. These ideas mainly use electromagnetic induction for the successful transmission of the required information. Here, you will find the great difference between Bluetooth/ Wi-Fi and NFC. The near field communication technology can be used in order to induce electric currents within passive components and just send the required data. Here, you can notice that the passive devices are of no need of their own power supply. They can be easily powered by the electromagnetic field produced by any active NFC component.

Benefits of the NFC technology

Just like any other wireless technology NFC also comes with significant benefits and some cons. According to domain experts, NFC technology has more potential or future benefits that are yet to be folded out.

·         NFC technology helps in quick and contactless data transfer just in one tap on the device screen

We hope that all the shared information in this article will be truly helpful to many. All industries are exploring more about the near field communication technology and we hope its benefits list is going to be longer in the near future. For sure, in the coming years, it is going to be a topping technology on the list.
