Near Field Communication (NFC), which enables an intuitive link between electronic devices, is an advanced wireless communication application technology that combines contactless authentication and Ad-Hoc networking technology based on RFID-related technology. The intuitive connection of NFC technology allows users to easily and securely transfer information, e-commerce, and other information simply by bringing two NFC devices close together, and interact and exchange information without the user's involvement in a complex configuration process. If you need to yell for everyone to have a private conversation with someone in a room full of people, your NFC device will set up an intuitive connection to allow a personal conversation with someone across a room full of people. For example, NFC technology allows users to plan vacation trips and book trains and hotels on their PCs. When you travel, bring your NFC device with near field communication close to your PC and your pre-booked train tickets and hotel reservations are stored on your phone or PDA. When you take a train or stay in a hotel, you can close your cell phone or PDA to the terminal of the ticket gate or the information desk without presenting your reservation or printing your ticket. Also, imagine that a user sees a concert advertisement poster of their favorite band. The user downloads information about the event from the poster's smart chip simply by bringing his or her mobile phone or PDA close to the poster. After finding out the information about the concert, the user can immediately buy a ticket and store the electronic ticket in his or her handheld computer device. On the concert day, the user can enter the concert venue without a ticket.

As such, NFC technology is a solution to complex information activities associated with real life, and provides intuitive access convenience for contact and execution by 'touch-and-start' operation for all types of user devices. (built-in security) Makes it easy for users to use payment / financing applications. Thus, NFC technology makes it possible to intuitively connect a computer, such as a mobile phone, an AV (Audio Visual) device, a digital camera, a PDA, a set-top box, or the like, so that all contents such as information, pictures, tickets, MP3 files, bookmarks, etc. Can be moved or operated.

This virtual NFC connection system is an open air interface platform that provides automatic configuration of wireless networks and wireless communication services for existing mobile phones, Bluetooth and wireless 802.11 devices. In other words, NFC devices set up and initialize heterogeneous wireless protocols such as Bluetooth, 802.11, and Wi-Fi. NFC devices can operate in either active or passive mode, allowing them to communicate extensively with a variety of passive devices such as contactless smart cards or RF tags.
