1. Development background:
Trailing robbery is one of the most common problems in robbery crimes at cash counters. Solving this problem has become a top priority for crime prevention in financial and other sectors. The linkage double-door interlock launched by Nanjing Tiger Gold Card Technology Co., Ltd. proposes to solve this problem. Quite effective solution.
2. Overview of the double-door interlocking system:
First, explain the concept of “double door interlocking”. The so-called double door interlocking linkage door means that two doors have the function of interlocking linkage, that is, when one door is opened, the other door will not be able to open, only when both doors are Only when it is closed can any of the doors be opened. According to bank safety management regulations, two doors must be set up at the entrance and exit of cash counters such as savings outlets, and employees must lock the first door in accordance with the regulations after entering the first door to enter the second door, such as entering the first door. If the door is not closed as required, employees will not be able to enter the second door. The purpose of this is to prevent criminals from stalking and committing crimes.
Bank robberies are usually criminals who use the method of trailing or coercing staff to enter the business hall to conduct criminal activities. No matter which method the criminals adopt, they must first pass through one or two channels in order to enter the business hall. Security doors, how to prevent crimes, the key lies in how to well control the security door access rights and quickly communicate the police information to the security department or the public security department. Nanjing Tiger Gold Card Technology Co., Ltd.’s linkage double-door interlock, has a very clever design for the control of safe access doors. It is specifically developed for criminals who use trailing or coercive methods to enter the business hall for illegal activities. A kind of fingerprint access control security controller.
Third, the principle of the double-door interlocking system:
Nanjing Tiger Gold Card Technology Co., Ltd. comprehensively examined the actual situation of the bank’s business hall, and designed a secure access door consisting of two anti-theft doors, two high-security locks, and two exit buttons (it can also be equipped with two exit card readers to swipe the card to exit the door. ), a linkage controller, two entrance card readers. The front and rear two anti-theft doors form a fully enclosed security aisle, two front and rear card readers (installed on the outside of the door), and two exit buttons (installed in the door), which replace the traditional key to open the door. When the card reader fails The door can also be opened with a key. In normal use, the staff swipes the card on the card reader. After the controller confirms the validity of the card, it opens the first door. After entering the passage, the first door must be closed before the anti-theft door can be opened through the second door lock.

When an employee exits, press the exit button to open the door. If a card reader is installed on the exit, the door needs to be opened by swiping the card. The process is the opposite of the above.
