什么是NFC?

NFC技术背景

NFC技术允许在两个相隔不超过10厘米且支持NFC功能的设备之间进行无线通信

非常便捷,该连接不依赖于Wi-F、4G、LTE或类似的技术,而且使用它不需要任何成本:不需要用户具备熟练技能;不需要电池;在不使用读卡器时不会发出射频波(它是一种无源技术);随着NFC技术在智能手机中的普及应用,每个人都可以享用NFC带来的好处。

NFC Forum(促进NFC和设备合规性的行业协会)帮助简化和标准化NFC的使用,以方便消费者。

NFC Forum称,在2020年初,地球上四分之一的居民(20亿人)拥有支持NFC功能的设备。每秒大约生产64台支持NFC功能的设备。这些设备通常是配备了NFC技术的智能手机。

赋予品牌生命

将数字生命赋予日常消费品成为可能 - 将支持NFC功能的智能手机靠近产品上的NFC标签,然后打开一个充满无限可能的伟大世界:网站、电话号码、社交媒体、忠诚度,优惠券派发、交易、比赛报名、产品识别,等等。

NFC技术还可用于保证产品的完整性,并在应用中验证其原产地,用例包括:

  • 消费者互动
  • 品牌保护
  • 防伪
  • 防盗
  • 产品标识
  • 访问控制/门禁
  • 资产追踪
  • 游戏

NFC技术背后的基础是什么?

NFC技术基于一种近距离接触或触碰体验。

用户将自己的智能手机靠近接触点,接触点内嵌的标签触发用户智能手机上的动作。NFC标签可以自动在智能手机上启动应用程序,而且通常通过移动网络或本地Wi-Fi连接到互联网获取额外信息。

FAQ about NFC technology

What is NFC technology?

Near Field Communication (NFC) is a contactless communication technology that enables two devices to communicate with each other over short distances of up to 10 cm. NFC utilizes radio frequency identity (RFID) technology and operates according to specific protocols and standards developed by the NFC Forum. NFC is a versatile technology that is used in various ways, such as for payments, data transfer, and access control.

How does NFC actually work?

NFC relies on a combination of two distinct technologies – Radio Frequency IDentification (RFID) and Near Field Communication (NFC). RFID refers to the technology that enables the reader or writer to detect the other device within its range. NFC refers to the protocols and standards developed by the NFC Forum that ensure the devices can actually communicate with each other. Together, these two technologies form the foundation of any successful NFC transaction.

Radio Frequency Identification (RFID) Technology
Radio frequency identification (RFID) works on a reader-writer principle. A reader or writer is typically attached to a smartphone or payment card. The reader sends out an electromagnetic field in a specific direction. Any device within range of this field will detect this signal and respond back with the appropriate data in accordance with the set protocol. It is through this back and forth communication process that the reader or writer extracts the required information.
Near Field Communication Protocols and Standards
The second component of NFC technology is the protocols and standards developed by the NFC Forum. These standards ensure that all compatible devices can correctly interpret each other's messages, allowing them to carry out successful transactions. One of the latest versions of these standards is called Wireless Charging Specification 2.0 (WLC 2.0), allowing wireless charging by enabling a single antenna in an NFC-enabled device to manage both communications and charging.

What are examples of applications using NFC technology

NFC technology is being utilized in many different ways, including for payments, data transfer, access control, and authentication.

Payments & Transactions
The most well-known use cases for NFC are payments and other financial transactions. Many banks have released credit cards with embedded NFC chips that allow users to make contactless payments simply by tapping their card against a reader or writer.
Data Transfer & Sharing
In addition to payments and financial transactions, NFC can also be used for other types of data transfer and sharing. Users can easily share photos, music files, contact lists, and other types of data between two NFC-enabled devices simply by tapping them together. This makes it quick and easy to send and receive files without the need for an internet connection.
Access Control & Authentication
NFC is also useful for access control and user authentication. Many companies use NFC tags to control access to certain areas of their premises, such as conference rooms or computer centers. Additionally, NFC can be used to securely store information such as passwords and user credentials. Learn more about Secure NFC solutions.
