What is Near Field Communication (NFC)
Near Field Communication (NFC) is a wireless communication technology that allows devices to communicate with each other over short distances. NFC is based on RFID technology, which enables communication between two devices when they are placed within a few centimeters of each other. 
NFC is commonly used for contactless payments, where a smartphone or other mobile device is used to make a payment by tapping it against a payment terminal. It is also used for a variety of other applications, including sharing information between devices, accessing digital content, and connecting to other wireless technologies such as Bluetooth.
NFC technology is built into many modern smartphones and other mobile devices, allowing them to communicate with other NFC-enabled devices. In addition, Near field communication tags can be embedded into a variety of products, allowing users to access additional information or services by tapping their smartphone against the tag.
Some examples of enabled applications include:
- Mobile payments: Users can make payments by tapping their smartphone against a payment terminal.
- Access control: can be used for security and access control, allowing users to tap their smartphone against a reader to gain access to a building or a restricted area.
- Marketing and advertising: can be used in marketing and advertising campaigns to provide additional information or offers to consumers.
- Social media: used to connect users to social media platforms, allowing them to check in at a location or share content with their friends.
- Product authentication: used to authenticate products, helping to prevent counterfeiting and improve supply chain security.
Overall, NFC technology offers a convenient and secure way for devices to communicate with each other over short distances, making it a popular choice for a wide range of applications.
