What is NFC Tag, and How Does It Work – Infographic

As digitalization emerges, Near Field Communication technology is becoming more popular and beneficial for businesses. It allows people to make contactless transactions, share contact information, track location, and verify users’ identities.

Besides, custom NFC tags enable you to connect wirelessly with others near you. You can also use it as NFC business cards, devices to unlock doors, and instruments to make payments.

What is an NFC tag?

NFC allows two devices to connect wirelessly and securely. It will enable you to exchange information between two devices by simply touching them.

NFC tags work at 13.56MHz and are RFID transponders. These tags are small chips that have an antenna attached. Each chip is unique and has an overwriteable memory. The chip can communicate with an NFC scanner/reader, such as an NFC smartphone, through the antenna.

How does it work?

NFC tags communicate via radio waves. NFC readers and NFC tags relay information using an NFC data exchange format. It transmits radio signals to activate and trigger the antenna in the receiver device. After the receiver device completes the validation, the information exchange takes place.

These devices do not require a battery but draw power from smartphones and other mobile devices. Like Bluetooth, NFC readers can connect to only one NFC tag at once. Smartphones can store card details, and the NFC tag acts as a transactional credit card.

NFC tags also improve transactions for consumers. With this technology, individuals will no longer be required to enter PINs to conduct cashless transactions. Throughout the pandemic, NFC tags facilitated contactless payments in public spaces.

NFC tags can also aid in reducing carbon footprint. It is an eco-friendly solution that can reduce a company’s carbon footprint. Paper-based NFC tags that are recyclable minimize the use of plastic in access cards. To know more about NFC tags, here is an infographic from NFC Tagify.
