Imagine a city where all processes can be carried out with just a single touch. You leave your house, touch your phone to the turnstile in the underground, and pay for your journey. A few minutes later, you’re at a shop purchasing coffee, again with your smartphone, and then you unlock your office door just as easily. This is not a distant future, but a reality already being implemented by NFC (Near Field Communication) technology, which makes city life more convenient, smarter, and comfortable for its residents.

What is NFC?

NFC is a wireless communication technology that allows data exchange between devices at a distance of up to 10 cm. It is simple, reliable, and, most importantly, secure. NFC has long been used in our smartphones for contactless payments, but its potential for smart cities is much greater. Dmitry Leus, an expert in corporate and financial management, says that NFC has a broader range of applications than it might seem at first glance. It can be used in public transport, healthcare, retail, as well as municipal and private taxi services. “This technology has a leading position in the contactless payment market”, Dmitry Leus commented.

One-touch interaction with public transport

Paper tickets and tokens are a thing of the past, as is searching for change to pay for travel. Now you can use your smartphone by simply placing it near a special sensor to pass through the turnstile. Such a mechanism is already in operation in London: the Oyster system combined with bank cards and smartphones allows millions of people to use NFC daily for travel payments. It is convenient and saves time. With NFC, there is no need for additional cards or cash; everything is managed via one device – your smartphone.

Infrastructure of the future and city digitalisation

Beyond transport, NFC can significantly simplify access to a variety of city services. For instance, you can access public bicycles or electric scooters using your smartphone. Or, NFC technology could facilitate access to libraries or clinic registrations. It acts as a universal key to all city services.

In Manchester, for example, NFC is already being used to ease access to cultural venues. Visitors can purchase tickets to museums and theatres via NFC without queuing, enhancing the overall comfort of city life.

Smart cities that fully integrate NFC will be truly digital. Every resident will have the opportunity to interact with the city’s infrastructure through their smartphone, whether paying for parking, registering at a hospital, or accessing office spaces. In London, smart street lights are already being tested, which can automatically adjust brightness depending on the time of day and the presence of people in the lit area through NFC. This is not only convenient but also energy-efficient.

How NFC protects your data

One of the main advantages of NFC is security. The technology only operates over short distances, minimising the risk of data interception. Additionally, NFC transactions are encrypted, so your financial and personal information is protected. Thus, every touch is not only convenient but also a safe, confidential process.

NFC technology is already changing cities today, and its potential is only growing. The smart cities of the future will use NFC not just for transport and public services, but also for energy management, security, and even ecology. So next time you use NFC on your smartphone, remember that this little touch is just the beginning of a significant transformation of our cities into the digital future.
