Development and innovation of NFC and RFID technology


Nowadays, mobile phones are the personal belongings of people's daily life. It even gradually replaces some life tools in people's daily life, such as keys, access cards, credit cards, tickets, etc., and through NFC technology, the functions of mobile phones are increasingly powerful.

   NFC (Near Field Communication) is not a new technology, but more and more related issues have recently been applied. Especially when the topic of third-party payment methods has been heated up, everyone is suddenly concerned about mobile phones. In the case of non-contact machines, the purpose of mutual sensing and payment is to use NFC technology. The most typical example is the bus card. What is NFC technology? Where is the application level?

What is the reason for the development of NFC? NFC is based on the integration of RFID (Radio Frequency Identification) and interconnection technology. What is the reason for the development of non-contact technology FC? NFC is based on the integration of RFID (Radio Frequency Identification) and interconnection technology. This is the development and innovation of non-contact technology and RFID technology. It is a short-range wireless communication technology standard.

Such as access control, tickets etc, users only need to carry a mobile device with a ticket or a gated password to access the reading device.

Contact confirmation, such as mobile payment, the user confirms the transaction by entering a password or simply accepting the transaction.

Contact connection, such as connecting two built-in NFC devices for point-to-point data transmission, such as downloading music, picture transfer and synchronous exchange of communication books;

With Browsing, a built-in NFC device can seamlessly and conveniently browse information stored in another NFC-enabled device.

At present, NFC is widely used in mobile phones. It is not new to use mobile phones to sense other devices to achieve wireless transmission. However, because mobile phones are already indispensable for modern people, applications that extend from mobile phones equipped with NFC functions are becoming more and more important. The more extensive. In terms of intelligent building category, what are the current applications of NFC on the access control system?

 In the case of access control, digitizing the access card (becoming a digital certificate) can be easily and securely sent to the designated user's mobile phone or other mobile device, and then manage the life cycle of the digital certificate through the mobile network and the cloud. For example, if a temporary staff member needs to enter or leave the building today, the management unit can send a “temporary” access control certificate to these staff members. When the set time is up, the access control certificate will be invalid, and the security will be undoubted.

The Internet of Things system collects data such as habits and usage patterns related to users, connects to an application (APP), and provides data analysis to the cloud or big data server to improve the quality of life of users and even provide products. Use and consumption information to manufacturers to predict consumer demand and improve product quality.

Regardless of the technology used, the biggest challenge is often to think about how to improve the experience and bring real convenience to users. If users change their habits to accommodate a certain technology, they will encounter certain obstacles. On the contrary, if technology can bring more convenient and better user experience, it will be able to do more with less, whether it is NFC, Bluetooth, Internet of Things or access control. Technology is the ultimate goal.
