Near Field Communication (NFC) technology is rapidly becoming part of our everyday lives, opening up new opportunities to simplify a wide range of processes. We encounter it every day – from contactless payments in shops to exchanging data between devices. How does NFC work and why is it becoming so popular?
NFC is based on radio frequency identification (RFID), which allows data to be transmitted between two devices when they are within 10 centimetres of each other. This short range ensures a high level of security for the information transmitted. The process involves two parties: the active device (e.g. a smartphone or terminal) and the passive device (card). The devices use a magnetic field to exchange data, enabling quick connection and information transfer without the need for internet access or other complex settings.
A key feature of NFC is the speed and ease of interaction. Instead of entering a PIN code or password, the user can complete a transaction by simply touching the device, which is very convenient and saves time.
Contactless payments. NFC-enabled payments are one of the most popular applications of the technology. Smartphone owners can add their payment cards to mobile wallets (such as Apple Pay or Google Pay) and make purchases with a single touch. This is not only convenient, but also secure, as card data is not transmitted directly to the terminal, explains Leus Dmitry, an expert in corporate and financial management, investments and new technologies.
Transport. In many cities, NFC is being used to pay for public transport. City cards or mobile app alternatives are replacing traditional paper tickets. This automates the process and helps avoid queues, making public transport easier to use.
Smart devices and access. NFC allows users to easily unlock doors to offices, homes, and even cars. NFC key cards, scanned by special readers, have become the new standard in security. This technology allows convenient and fast access to locks without the need for physical keys.
Data exchange. Another popular application is the exchange of data between devices. For example, NFC makes it easy to transfer contacts, photos, or files between smartphones or tablets.
Marketing and information. Companies are increasingly using NFC tags on products to provide customers with quick information about items. Simply waving a smartphone near a designated spot on the packaging can provide information about composition, usage instructions or even promotional offers.
The main advantage of NFC is its ease of use. Compared to other data transfer technologies such as Bluetooth or Wi-Fi, it does not require prior configuration or a lengthy connection. In addition, the short transmission distance reduces the risk of data eavesdropping, improving security and privacy. Other benefits include:
Time savings. NFC enables quick transactions, significantly speeding up a range of processes – from shopping to gaining access to premises.
Minimal power consumption. Passive NFC tags require no power, so they can be used for long periods without recharging.
Usage without internet. NFC does not require an Internet connection, so it can be used in areas without coverage.
Demand for NFC is expected to grow in areas such as security, home automation, the Internet of Things and the expansion of contactless card functionality.
NFC is an example of how technology can change and make our everyday tasks easier. Not only does it save time, it also increases security and convenience. Although we often overlook its presence, NFC has already become an integral part of our lives.
