Three basic application types of NFC

Release Time:

2020-09-07

As a near-field communication technology that has been popular in recent years, NFC has been widely used. NFC applications can be roughly divided into three basic types. Let the editor take you closer to these three basic types of applications.NFC logo1. Payment applicationNFC payment applications m

1. Payment application

NFC payment applications mainly refer to the applications of mobile phones with NFC functions simulating bank cards and one-card cards. The NFC payment application can be divided into two parts: open-loop application and closed-loop application.

The application where NFC is virtualized into a bank card is called an open-loop application. Ideally, a mobile phone with NFC function and a simulated bank card can be used as a bank card to swipe the mobile phone on the POS machine in supermarkets and shopping malls. However, it cannot be fully realized in China at present. The main reason is that the NFC payment under the open-loop application has a complicated industrial chain, and the interests of card vendors and solution providers behind it and the game of the industrial structure are very complicated. As far as the current domestic NFC open-loop application environment is concerned, due to the game of various interests, the NFC open-loop payment application has missed the best opportunity before mobile payments such as Alipay and WeChat payment became popular, and it is extremely difficult for NFC open-loop payment to continue. developed individually. Its development can only occupy a place in the future mobile payment if it seeks to connect and bundle with Alipay and WeChat Pay as a means of assisting Alipay and WeChat Pay in identity authentication.

NFC模拟一卡通卡片的应用称为闭环应用。目前NFC的闭环应用在国内的发展也不太理想，虽然在有些城市的公交系统已经开放了手机的NFC功能，但并没有得到普及。根本原因是以卡为载体的一卡通系统存在发卡获利。系统集成商和运营商(公交集团及学校等)在发卡上可以获得丰厚的利润。因而目前小米等手机公司虽在一些城市试点开通了手机的NFC公交卡功能，但一般都还需开通服务费。但相信随着NFC手机的普及和NFC技术的不断成熟，一卡通系统会逐渐支持NFC手机的应用，闭环应用会有一个光明的前景。

2.安防应用

NFC安防的应用主要是将手机虚拟成门禁卡、电子门票等。NFC虚拟门禁卡就是将现有的门禁卡数据写入手机NFC，这样无需使用智能卡，使用带NFC功能块的手机就可以实现门禁功能。NFC虚拟电子门票的应用就是在用户购票后，售票系统将门票信息发送给手机，带有NFC功能的手机可以把门票信息虚拟成电子门票，在检票是直接刷手机即可。NFC在安防系统的应用是今后NFC应用的重要领域，前景十分广阔。NFC在该领域的应用不仅可以节约运营商成本，而且可为使用者带来不少便捷。使用手机虚拟替代实体门禁卡或者磁卡式门票可以一定程度减少两者的制作成本，同方便用户开卡刷卡操作，一定程度提高自动化程度，降低开卡人员雇佣资金和提升服务效率。

3.标签应用

NFC标签的应用就是把一些信息写入一个NFC标签内，用户只需用NFC手机在NFC标签上挥一挥就可以立即获得相关的信息。例如商家可以把含有海报、促销信息、广告的NFC标签放在店门口，用户可以根据自己的需求用NFC手机获取相关的信息，并可以登录社交网络、和朋友分享细节或好东西。

Although the application of NFC tags is very convenient and the cost is very low, the application prospect of NFC tags is not optimistic with the popularization of mobile networks and the gradual popularity of QR codes. Because compared with NFC tags, QR codes only need to be generated and printed into a small image, which can be said to be almost zero cost. The information provided is as rich as NFC , and it can easily replace the use of NFC tags.
