ATM anti-theft card system overview:

ATM self-service bank is unattended and provides financial services 24 hours a day. The security of its associated equipment and customer transaction process has always been an important work of the bank's security department. And with the large-scale use of ATMs in the financial industry, some problems have gradually been exposed, which seriously restricts the development of ATM to a deeper and higher condition. At the same time, there have been an increasing number of ATM accounting disputes and ATM financial crimes. In order to strengthen the safe operation and management of bank-owned ATMs and self-service banks, to save resources to the greatest extent and reduce the cost of operation and manpower management, in accordance with the principle of "safety, economy and stability", the use of remote network communication technology and ATM anti-theft card Analyze technology and build ATM machine / self-service bank local and remote intelligent ATM anti-theft card management system.

In recent years, ATM machines / self-service banking crimes have emerged in an endless stream. The criminal methods are specifically as follows: ATM machines are equipped with stolen code devices or illegal card reading devices, and user accounts and passwords are stolen. However, the existing ATM monitoring methods are limited by network bandwidth, security manpower and other conditions, and can only achieve forensic evidence afterwards, and cannot find suspicious behavior in real time and report to the police in time.

With the maturity of ATM smart anti-theft card products, bank security systems began to develop from the digital stage to the network and intelligence. ATM machine / self-service bank local and remote intelligent anti-theft card management system is designed and developed according to the current situation of bank network bandwidth and the new situation of ATM / self-service bank security. The system analyzes products through ATM anti-theft cards, automatically and effectively discovers abnormal behaviors in time, and generates corresponding alarms. At the same time, the system is based on the design idea of ​​"more monitoring, less transmission, with alarm upload, and no alarm polling". Only when there is an alarm in the front end, the system generates the alarm information to the control center. When there is no other alarm situation, you can select the round robin mode to upload the alarm information according to user needs. This solution can not only save bandwidth to the maximum extent, reduce the cost of system use, but also save manpower and ensure that the alarm situation is discovered in time.

This system can not only maximize the safety precautions, fully meet the requirements of the bank, consider the comprehensive benefits, but also ensure that the system has a moderate lead, while also improving management efficiency.

ATM monitoring technology information usage program example Global Security Network Comment With the rapid development of the financial industry, banking services have surpassed the traditional service concept, atm ATMs continue to spread throughout China, it has brought many conveniences to our lives and become our life. The inseparable assistant has been fully integrated into the daily life of the people.

Based on years of practical experience, Nanjing Yuantuo Technology Co., Ltd. has worked out how to protect the safe use of bank atm, reduce bank and customer disputes, protect the interests of customers and banks, and prevent various crimes against atm.

can.

Atm anti-theft card needs to be completed

1. Supervise whether the card insertion port of the ATM machine is working properly and whether the withdrawer is withdrawing money. It is difficult for the ATM machine to swallow the card to minimize disputes between banks and depositors.

2. As most ATMs are in an unattended environment, it is necessary to supervise and prevent the illegal destruction of illegal installation of card theft devices, and provide an effective basis for triggering an alarm at any time.

3. Surveillance and prevention of very few criminals using high-tech means to copy, embezzle, forge depositor's savings card to steal depositor's money through atm, and provide an effective basis for the public security organs to obtain evidence afterwards.

ATM anti-theft card system requirements research

Since the unattended self-service bank is mainly an ATM cash machine, and the special structure of the ATM machine and the application environment and the variety of machine model parameters, the unmanned self-service bank monitoring equipment selection and installation of special conditions are proposed. And the use environment, monitoring objects, external interfaces and other differences, atm anti-theft card has many functional characteristics, at the same time, we need corresponding special technical information to solve these special functions.

1. Atm machine itself is mostly exposed outdoors, and it is unattended. The design scheme of the conditional atm machine is anti-riot and non-portable. The same condition atm anti-theft card also has these characteristics.

2. The ATM machine provides 24-hour service and is unattended. The ATM card can work steadily and continuously for 24 hours.

Atm anti-theft card working principle The anti-theft code system consists of a microcontroller module, a laser ranging module, a human activity monitoring module and an Internet of Things interface circuit. Among them, the human activity monitoring module is responsible for monitoring whether there are people around the ATM machine. When someone is in front of the ATM machine, the module sends a pause scan command to the system. At this time, the system will no longer perform laser ranging on the ATM machine; when the person leaves, the system immediately detects the ATM machine. Once a card theft device is detected, the system immediately sends an alarm signal to the monitoring center until the relevant staff removes the card theft device to stop the alarm and return to normal working conditions. At this time, the anti-theft code system will monitor and scan the ATM machine at regular intervals according to the user's settings.

Anti-theft code system real-time alarm case
At 18:40 on May 10, 2010, in front of a teller machine at a bank in Baixia District, Nanjing, a thin and tall man tested the card with the teller, then took out a black plastic block and stuck it to the card slot. A short man took out the wire slot, glued it on the top of the cash machine, and installed an MP4 camera on the top of the teller machine. The whole process took less than 5 minutes.
Five minutes later, the police who had received the report from the ATM monitoring system quietly came to the ATM and closely monitored the ATM. Two hours later, the two criminals walked to the teller machine to clean up the crime tools and were caught by the police on the sidelines.
After interrogation, the two suspects were all from Wuhu City, Anhui Province. They had committed crimes in Jiangxi and Hunan by installing pirates and cameras for more than 10 cases, stealing 210,000 yuan of money. They arrived in Nanjing this time and were caught as soon as they reached out.
2. Ordinary video surveillance encounters unsolvable problems. At present, most ATM video surveillance systems on the market are often in a state of "monitoring without control". There are many loopholes, which cannot really achieve the expected effect of protecting the safe operation of ATMs and the interests of depositors. .
The biggest problem that cannot be solved by ordinary video surveillance is that the criminals' crime tools are upgraded and the means are increasingly renovated. For example, the most common and most effective crime means are: installing a pirate coder, a fake keyboard, a camera on the ATM machine, and stealing the cardholder password However, the video monitoring response of the ordinary ATM machine lags behind, only recording, can not report to the police in time, to stop the case.
3. Analysis of the characteristics and advantages of Yuantuo's anti-theft code system In view of the increasingly rampant bank card criminal activities, Yuantuo has recently developed a high-performance "anti-theft code system" to overcome the weakness of existing video surveillance that can only record but not alarm, accurate The alarm signal is issued in time to stop the occurrence of card theft and protect the interests of banks and withdrawers.
Analysis of crimes The most common and most harmful crimes are: criminals install stolen code devices at the card slots and keyboards of ATMs to steal cardholder numbers, and install cameras to steal passwords.
Traditional monitoring equipment used the principle of infrared light reflection to punch a light hole around the card slot of the teller machine, and emit infrared light from the inside of the self-service equipment through the light hole. If there is obstruction, it is determined that there is a code thief. But this way destroys the structure of the teller machine, and as long as the ambient light changes, or there are foreign objects blocking the light hole, etc., it is easy to misreport; if the criminals install a card theft to avoid the light hole, it will also miss the report. Later, there were also electromagnetic field, image processing and other technologies to identify stolen code devices, all of which were discarded due to false positives and false negatives.
The working principle Yuantuo believes that the installation of any stolen code equipment will change the height of the important parts of the teller machine. If the height of these important parts is monitored by high-precision measuring instruments, it can be judged whether a stolen card device is installed. To stop the case.
"Anti-theft code system" uses laser ranging technology, first multi-point ranging for the ATM's card slot, keyboard and other important parts, and save the measurement results as a reference value, and set to re-ranging every 10 seconds, when When the measured distance value does not exceed the alarm distance parameter value, the current state is maintained; once the fraudulent element installs a stolen device or keyboard, and the measured distance value immediately exceeds the alarm distance parameter value, the anti-theft card control module will start within 2 seconds SMS alarm, security room alarm, live voice and siren report within 5 seconds. This product can be installed on the top of the ATM or the ceiling of the self-service bank. It is easy to install and has good concealment; Accurate laser ranging, forming a laser protection net, and full-duty monitoring, the monitoring distance is from 0.05 meters to 200 meters, the monitoring range is large, and it is not affected by electromagnetic, environmental, and severe weather. The problem of false positives. This system is also equipped with an Internet of Things module, which can monitor the status of the ATMs of various business outlets in time through the network of the monitoring center, and promptly report the abnormal situation in a timely manner.
The key features and advantages of technical parameters apply to all tellers;
After detecting the stolen code device, it will send out an alarm signal in time;
Good concealment, avoid attack by criminals;
Full attendance monitoring, easy installation;
Accurate ranging and wide monitoring range;
