Card recognition is divided into two categories: the first one is a magnetic card, but the magnetic card is low in security, easy to wear and requires frequent magnetization; the second is an RFID card, which is cheap, easy to use, highly secure and can use a database. It is well managed, its cost performance is extremely high, and it has a good promotion prospect.
The working principle of the whole access control system is: one person and one card, and establish corresponding personal information in the database management system according to the serial number of the card. When the door is to be opened, the card is brushed on the lower computer, and the RFID gate reader transmits the serial number to the upper computer server. The server queries the corresponding personal information in the database according to the serial number and transmits it to the lower computer.
At the same time, the lower computer reads the data of the fixed sector block of the card (reading the card), compares the read data with the data sent by the upper computer, and opens the door exactly the same, otherwise the LCD displays an error and does not open the door.
The overall software design of the access control system includes the software design of the lower computer reader and the software design of the database management system of the upper computer. The access control system of the access control system is mainly to realize the reading of the card and the communication with the host computer management system, and is implemented by C language programming in the Keil4 environment.

The security industry and RFID technology are inextricably linked. RFID technology plays an important role in the application of products and solutions such as intelligent transportation, smart parking, smart access control, and radio frequency anti-theft.
The barcode technology attaches the barcode information to the article, and scans the barcode on the article through the scanner to obtain the information of the article. The RFID technology attaches the RFID tag to the article, and reads the information in the tag into the RFID reader through the radio frequency signal, thereby obtaining the unique information of the article.
Overall, the main markets for domestic RFID applications are in the areas of identification, traffic management, military and security, asset management, and logistics and warehousing. And in the application of RFID in foreign countries, the absolute main force of retail and transportation logistics. The sum of the two is about 40% of the entire market. Garment applications have been fully deployed in apparel and retail outlets such as Wal-Mart, Metro and Zara.
Specifically, companies need to affix printed RFID tags to each item that needs to be identified, and also need to be equipped with relevant identification devices such as channel machines, handheld terminal, and the like. In addition, enterprises need to integrate RFID with the original ERP system, and the business process will be more complicated than before, and production, transportation and warehousing should be coordinated.
In the short term, “unmanned retail stores” are still hard to become the next explosion point of RFID technology, but it is a new attempt of RFID technology in the field of consumer retail. Of course, RFID technology is just one of the many reasons for the “unmanned retail store” to attract attention. The value of this new retail form is also the collection of big data for offline consumer spending.
