Access control is very important for enterprises and schools. In addition to being used as general access control, Zhengdafei smart card can also store small sums of money and cooperate with general stores to improve the functionality of cards, such as a British access control system manufacturer. The Zhengdafei smart card originally used on the access control can be applied to the cash dispenser at the same time, which combines the functions of the access control and the electronic wallet.

The overall structure of the access control system consists of two parts: the upper computer server management system and the lower computer card reader. The lower computer card reader mainly consists of power supply, main controller, liquid crystal display, read/write card module, antenna and serial communication. The M102GPCV3 reader card module uses 13.56MHz non-contact RF technology and can read MifareOneS50, S70, FM11RF08 and compatible cards.

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 lower computer 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 error is displayed on the liquid crystal and the door is not opened. Similarly, when the Zhengdafei smart card is used for consumption, the corresponding user personal information is established in the database management system according to the serial number of the card. When the card is to be swiped, the card is swiped on the lower computer, and the lower computer reader transmits the serial number to the upper computer server, and 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 deducts the same exactly, otherwise it will prompt the error message and cannot deduct the money. The information will be uploaded to the upper computer management system for saving.

Therefore, the Zhengdafei smart card used on the access control can be applied to the cash dispenser at the same time, which combines the functions of the access control and the electronic wallet.
