Bank card with access control function

According to the query of the World Wide Web, there are more than 5,000 households in the post-modern city community on Baiziwan Road. At the beginning of community design, the "postmodern" housing concept based on fashion and openness has not been closed. Seeing that the occupancy rate of residential quarters is getting higher and higher, and the mobility of personnel is getting stronger and stronger, the property decided to carry out closed management transformation of residential quarters from the second half of 20 14. However, it takes money to install fences and transform access control, and the residential property is very worried about where the money comes from. After learning about this incident, the Bohai Bank Postmodern City Sub-branch, which just entered the community, offered to sponsor the property to update the access control system. After consultation, the two parties decided that the new access card could be divided into two types, one is a common card with a single access control function, and the other is a financial IC card with all the functions of the Bohai Bank debit card, which residents can choose voluntarily. 20 yuan/Card deposit is charged for ordinary access cards, and no deposit is charged for bank access cards. The new access card will be used for entering and leaving the community gate, building door and garage door. By the middle of 20 15 10, 700 ordinary access cards and more than 700 bank access cards were issued.

Basic definition of access card The original intelligent access control system consists of a host, a card reader and an electronic lock (computers and communication converters are added when networking). The card reader is a contactless card reader. Only when the cardholder quickly swings the card near the card reader (5- 15cm) can the card reader sense that there is a card and guide the information (card number) in the card to the host. The host examines the illegality of the card before deciding whether to close the door.
