Using a wireless technology known as Near-field communication (NFC), once activated on the smartphone, allows payments or purchases to be made at select stores.

What is Near-field communication (NFC)?

NFC is a set of short-range wireless technologies that typically require a distance of 4 cm or less to initiate a connection.

Characteristics of Near-field communication (NFC)

For it to work, it is necessary to place two spiral-type antennas within these close electromagnetic fields.

This technology is built on radio frequency identification, which allows a gadget to send radio waves to another gadget or another tag and trigger a certain action.

The NFC acts on the smartphones just like the RFID chips of the bank cards with which you can make payments or purchases.

Therefore, we can conclude that the NFC allows two devices to exchange data when in close proximity to each other.
