nfc what does it mean

nfc refers to near field communication, also called short-range wireless communication. Devices using NFC technology can exchange data when they are close to each other. It is integrated by non-contact radio frequency identification and interconnection technology. Evolved, by integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, mobile terminals are used to realize mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications.

The origin of near field communication

In 2003, Sony and Philips Semiconductors (now NXP Semiconductors) Cooperation, plans to develop a more secure, faster and compatible wireless communication technology based on contactless radio frequency card technology.

The principle of near field communication

Near field communication is a short-distance high-frequency wireless communication technology. Devices using NFC technology (such as mobile phones) can Data exchange occurs when in close proximity to each other.

Near field communication form

1. Point-to-point form

Point-to-point mode, in this mode two Several NFC devices can exchange data. For example, multiple NFC-enabled digital cameras and mobile phones can use NFC technology to wirelessly interconnect to realize data exchange such as virtual business cards or digital photos.

2. Card reader mode

Read/write mode. In this mode, the NFC device is used as a contactless reader and writer. For example, a mobile phone that supports NFC plays the role of a reader and writer when interacting with tags. A mobile phone with NFC enabled can read and write tags that support the NFC data format standard.

3. Card simulation form

Simulation card mode, this mode is to simulate a device with NFC function into a tag or contactless card. For example, a mobile phone that supports NFC can be used as an access control card, Bank cards, etc. are read.

Near field communication application

1. Payment application

NFC payment mainly refers to the payment with NFC Applications in which functional mobile phones are virtualized into bank cards, all-in-one cards, etc., and applications in which NFC is virtualized into bank cards, are called open-loop applications. Ideally, a mobile phone with NFC functions can be used as a bank card at POS machines in supermarkets and shopping malls. Use your mobile phone to make purchases.

2. Security Application

The main application of NFC security is to virtualize mobile phones into access control cards, electronic tickets, etc. The NFC virtual access control card is to write the existing access control card data to the NFC of the mobile phone. In this way, the access control function can be realized using the mobile phone without using a smart card. This not only makes the configuration, monitoring and modification of the access control very convenient, but also enables remote modification. and configuration, such as temporary distribution of voucher cards when needed, etc.

3. Tag application meaning

The application of NFC tag is to write some information into an NFC tag. The user only needs to wave his NFC phone on the NFC tag to get the relevant information immediately. Information, for example, merchants can place NFC tags containing posters, promotional information, and advertisements at the door of the store. Users can use NFC phones to obtain relevant information according to their own needs, and can log in to social networks and share details or goodies with friends.
