NFC Applications

Near Field Communication Technology solves various problems faced at different points across multiple industries. A few specific places where NFC is applied are listed below.

1. Contactless Payments

The most commonly used Google Pay is one of the best examples that uses NFC. Near Field Communications make transactions fast, easy, safe and secure. It allows mobiles, tablets, laptops, smart watches, and other Androis and iOS devices to make payments as it can communicate with NFC-enabled readers. The transaction by NFC is initiated not by reading a magnetic stripe on a card, but by having an NFC reader send a signal that’s picked up by an NFC antenna on an NFC-enabled device. Through a point-of-sale (POS) system, the reader is initiated and the transaction takes place. They are convenient for businesses and customers.

2. Transit

NFC technology could be enabled in public transport systems for ticketing purposes. We must have observed just striking a card or scanning a QR code while getting into a metro train. Here, very quick transactions take place in a fraction of a second and the amount for your travel is deducted. Near Field Technology can play a crucial role in these places. NFC should be enabled in your smart card which is read by a receiver placed at the station. Instead of a smart card, it can also be linked to a smartphone wallet or a QR code. It can also be enabled on other devices such as smartwatches.

3. Attendance

Another application of the Near Field Communication is to record the attendance. The working is similar to the previously mentioned applications, except it involves no transaction of money. When the signal is exchanged between the sender and receiver, the attendance is marked. The NFC enabled mobile device or a smart card initiates the signal when scanned at the entry point. The NFC tag sent is received by the receiving antenna at the entry. This quick process can record the entry time along with other particulars to record the attendance.

4. Access Control

There is always access cards in companies to allow respective people into the particular office space. NFC Technology can play a vital role in such access control eliminating any huge set ups. Instead of cards, mobile applications in the smart phones could be used to open the doors. NFC can identify people who access select floors and areas. Not just in office, this application can be used in hotels too to avoid tedious check-in process. The customers can check-in via a mobile application. When approved, they can use their smart phones to open the doors that are NFC-enabled. This can reduce labour and also eliminate keys or key cards.

5. Security system

The most common verification systems used are the One Time Passwords (OTPs). NFC can simply serve as an alternative. NFC tags and companion mobile applications can be used to create a verifiable repositories. When NFC tags in your laptops, PCs or website logins is scanned, the signal exchanged can verify the identity easily. This little scan is an easy process and acts as a safety barrier.

Similarly, the same mechanism can be applies in different places like trials, checkpoints, ticketing, product status, etc.

Communication and data transmission play a vital role in today’s digital era. It makes the transmission of information possible from one device to another and from one place to another. With a large amount being stored and transmitted every day, it requires proper communication protocols. Communication has been evolving constantly. We’ve come a long way from using messengers to wired communications and then to wireless modes. Yet, we still keep advancing in various wireless methods of communication. Wireless communication is the transfer of data eliminating the use of wires and cables. The different types of wireless communications include satellite communication, infrared communication, broadcast radio, microwave communication, Bluetooth technology, etc. One such advanced technique is the Near Field Communication or NFC. NFC is used for the transmission of data using radio waves especially, for shorter distances.
