The entire world is going through a tremendous digital transformation due to the advent of revolutionary technologies. People are getting used to with the web, mobile, IoT, Wireless, and other smart devices to automate and simplify their tasks and eventually their life too.

NFC (Near Field Communication) is the advanced technology that has received more attention by media since it has proved its potential for creative marketing and mobile payments. Considering the increasing popularity and usage of NFC tags, smartphone manufacturers have started producing the mobile devices that support the NFC technology. Here you can have the answers to your what, how and where questions related to NFC tags and technology.

What Is NFC?

Enjoy the instant access to varying information related to various services, products, people and landmarks using the power of NFC. Well, it’s not something like rocket science. It’s one of the wireless radio communication technologies like Wi-Fi and Bluetooth. This technology was already there, but it was not able to gain enough response from the market and users.

NFC technology enables users to set up phone-to-phone communication to store and transform information. NFC supported devices can work for you as a contactless payment system, social networking, and promotional platform.

NFC tags are one of the essential parts of this technology. It allows users to transfer the data within a maximum range of about 4cm. Due to narrow ranges, NFC tags are largely used for the promotion of versatile products, services or items.

How Do NFC Tags Work?

NFS tags are small units that contain embedded chips within them. The NFC tags allow users to get connected with smartphones and transfer the data and instructions on them. Sometimes, it refers as smart tags. If we talk about the functionality of NFC tags, they are a bit similar to smartphones. The only difference is it offers one-way communication that is from the tag to the receiving device.

Moreover, NFC tags are passive devices that operate without a power supply. To process anything, they rely on active devices like smartphones. Basically, NFC tags can’t really do any processes of their own. They simply transfer the data or information to a nearby active device.

Electromagnetic induction is used to generate power and create a current in NFC tags. To inject power into NFC tags, coils of wire can be used to produce electromagnetic waves that can be picked up or turned back into current by a coil of wire. It’s a common tactic that is used for almost all wireless charging technologies.

Active devices are responsible for producing a magnetic field in NFC tags. A simple coil of wire generates magnetic field perpendicular to the flow of the altering current in the wire. The strength of magnetic field relies on the number of turns in the wire coil or increasing the current flowing through the wire. To produce more current, excessive energy and the high power requisites are required that would not be suitable for battery powered mobile technologies. This is the reason NFC operates within a limited geographical range.

The passive devices work in a similar way but in reverse order. When the passive device is in the range of active device’s magnetic field, the electrons in the receiving coil of wire starts producing a current that matches with the transmitting smartphone. Of course, some power loss is always there through the air, but the current generated is enough to give power to the circuitry in the NFC tags.

Real-time Implementations of Smart NFC Tags


Set NFC tag at the entrance of your home that enables you to turn off and turn on your Wi-Fi, Bluetooth or ringer volume.


Play your workout special music using the tags. All you need to do is stick your tag in your sports bag, turn on flight mode, and launch your workout playlist. Using “toggle,” you can follow the reverse process by tapping on the tag again while you have done with your workout.


Put a tag on your office desk that allows you to turn off the sound of your smartphone or set it in vibrate mode, turn on your Wi-Fi, etc. Using another tag, you can drop a message to your partner that you are leaving the office and will reach home soon.


If your car is having advanced amenities of Bluetooth connection and radio or headset, the NFC tag allows you to turn on your Bluetooth, so your smartphone directly gets connected with your radio or headset and plays your favourite music.
