What is NFC?

Near Field Communication (NFC) technology has become an integral part of our daily lives. It is a wireless communication technology that allows two devices to exchange data when brought close together. NFC technology has a wide range of applications including contactless payment, transport ticketing, access control and more.

One of the most exciting uses of NFC technology is NFC tags. An NFC tag is a small electronic device that can be programmed to store and transmit data. NFC tags can be used in a variety of ways, including marketing, advertising and logistics. In this article, we will specifically explore the basics of NFC tags, how they work and their applications.

What is NFC Tag?

An NFC tag is a small electronic device containing a microchip and an antenna. The tag is programmed to store and transmit data when brought near an NFC-enabled device such as a smartphone or tablet. NFC tags are available in a variety of shapes and sizes, from stickers and wristbands to key rings and cards.

How Does NFC Tag Work?

An NFC tag works using electromagnetic induction. When an NFC-enabled device is brought close to an NFC tag, the device generates a magnetic field that powers the tag. The tag then sends back a signal containing the data stored on the tag. The NFC-enabled device reads and writes data to the tag depending on the permissions granted to the device.

The NFC tag is programmed with various types of data, including web links, contact details, product details and more. The data is read by an NFC-enabled device, which can then perform various actions based on the data. For example, an NFC tag programmed with a web link can direct a smartphone to a website, while an NFC tag programmed with contact information saves the information in the phone's contacts.


NFC tags have a wide range of applications, from marketing and advertising to logistics and transport.

  • Marketing and Advertising:

It is used to provide customers with additional information about a product or service. For example, a tag placed on a product can direct customers to a website where they can learn more about the product.

  • Access Control:

It can be used for access control in buildings, hotels and other facilities. An NFC tag is programmed to grant access to authorised personnel and deny access to unauthorised persons.

  • Transport Ticketing:

It can be used for transport ticketing and passengers simply tap their NFC-enabled device on a reader to pay their fare.

  • Sağlık hizmeti:

It is often used in healthcare to track patient information, medication schedules and more. An NFC tag can be placed on the patient's wristband and the data stored on the tag can be used to track the patient's medical history and medication schedule.
