As a widely used automatic identification technology at present, RFID technology has not only been successfully applied in traditional manufacturing, retail and other fields, but has also made innovative progress. At the same time, it also has a very outstanding performance in the field of security, especially in Access Control and attendance, parking lot management, car intelligent anti-theft, electronic patrol, etc., and it has fully realized precise security and smart security!

Application of RFID technology in security field

1. Access control attendance

Access control is the most widely used field of RFID in the security industry. RFID technology is often used in physical access control of many government, corporate and campus institutions. These can range from simple access control solutions to multifunctional card solutions such as e-wallets or for book lending.

An open access control system is installed at the entrance of large conferences and the passages of important event places. When participants or other people entering and exiting the passage pass, the system automatically senses the RFID electronic tag invitations or ID Cards held by the personnel. , to confirm the identity of the personnel entering and exiting. Legal users pass through normally, and at the same time, the identity information of the passers-by and the photos captured on the spot are displayed on the display screen instantly, and the guards on duty can compare and confirm. When a person without a relevant identification certificate or a person with an illegal certificate passes through, the system equipment will prompt an alarm, and the guards can prevent them from entering in time. For Sports venues, concerts and other leisure and entertainment facilities, RFID equipment and systems can provide a series of access control functions for ticket management. In this way, losses caused by ticket forgery can be reduced. Tickets can be made with simple cards with RFID technology by barcode printers, and RFID Cards can also be made into membership cards, monthly cards or annual cards; and the tickets do not need to be taken out, just put on the body to read, Realize open access control management.

RFID open access control equipment not only has all the functional characteristics of traditional ordinary access control equipment, but also has the characteristics of open multiple people passing through quickly and recording the personal information of each entry and exit at the same time. When a person wearing a radio frequency identity card passes through the gate, the information in the identity card is automatically collected by the system without manual intervention, making access control management more convenient. The electronic tag card has a long service life, can be read and written repeatedly more than 100,000 times, and has a service life of more than ten years.

2. Parking lot management

RFID technology provides independent and uninterrupted reading services for the management of the parking lot, ensuring that only licensed vehicles can pass through, realizing the digital management of parking services and fee collection. The use of RFID technology for parking lot management can realize the control of all vehicles in the site and realize the information management of computerized vehicles. In the case of no one on duty, the system automatically records the time of entry and exit of vehicles and the license plate number, provides a complete record of the time of entry and exit, strengthens the control and management of overdue vehicles, and speeds up the timely search and delivery of vehicles. Use the portable reader to collect and grasp the garage status and parking space information.

Part of the non-parking automatic toll collection system using RFID technology is a microwave signal identification device, that is, the entrance and exit communicator, which can be installed above the control vehicle entrance and exit. The other part is the electronic tag. The system is equipped with a registered electronic tag for each parking user. It can be installed in a proper position in the front windshield of the vehicle. There is an identification code inside the module. When the vehicle arrives at the entrance of the community, the vehicle detector detects the presence of the vehicle, starts the entrance communicator, and detects the identity code (ID) in the electronic tag of the coming vehicle. The ID is loaded in the form of microwaves and transmitted to the communicator. If The ID code in the owner's electronic tag is preset in the information database of the communicator, indicating that the tag belongs to the parking lot, then the brakes will be opened quickly and automatically, and the vehicle can pass without stopping. The use of RFID technology for non-contact rapid identification of vehicles and automatic identification and comparison of user identities ensures the safety and protection of personal property and the simplicity and speed of normal entry and exit procedures.

3. Automobile intelligent anti-theft

At present, the anti-theft of automobile products can be divided into four categories: mechanical, electronic, chip and network. Although each has its own advantages and disadvantages, the development direction of automobile anti-theft is towards the more intelligent chip and network. RFID car intelligent anti-theft mainly adopts chip anti-theft, which is a small enough radio frequency card that can be packaged into the car key and contains a specific code word.

The application of RFID technology in the field of car anti-theft can simultaneously lock multiple points such as vehicle circuits, oil circuits, and engines. By encapsulating a radio frequency card containing a specific codeword in the car key, a reader is installed on the car. When the key is inserted into the ignition, the reader can identify the identity of the key. If the reader cannot receive the specific signal sent by the radio frequency card, the central computer will shut down the car engine. Just can prevent present common car theft behavior easily with the method for this electronic verification.

In addition, the driver has a radio frequency card, and its transmission range is within 45 to 55 centimeters of the driver's seat. The reader is mounted on the back of the seat. The engine can start only when the reader/writer reads a valid ID number. When the driver takes the radio frequency card away from the car and the reader cannot read the valid ID number, the engine will automatically shut down and the alarm device will be triggered at the same time.

4. Commodity anti-theft

Commodity anti-theft is the most widely used related product of RFID in the field of anti-theft alarm. The application fields include department Stores, supermarkets, books and various industries, especially in large supermarkets (storage). RFID commodity anti-theft generally uses RFID automatic identification technology to assign a unique electronic identification code to the commodity. By setting the RFID anti-theft door at the exit to automatically identify the status of the commodity (book/goods), it can effectively protect the commodity and prevent theft of the commodity.

Product label printing and RFID writing are carried out through the RFID printer, realizing one product with one label, and giving the product a unique RFID code. By setting intelligent decoding on the RFID reading and writing terminal, when paying/borrowing/returning books/in and out of the warehouse, put the product on the intelligent decoding terminal to read and automatically realize the decoding, so that the product can freely pass through the anti-theft detector at the entrance and exit. An anti-theft passage door is set at the entrance and exit, and undecoded goods pass through the RFID anti-theft passage door, which automatically triggers a detector alarm.

5. Electronic Patrol

Electronic patrol is mainly aimed at the automatic management of security personnel's patrol. Generally, long-distance fixed-point signs will be placed on the patrol route, and the patrol device worn by the security guard contains a long-distance identification module. When the security guard arrives at the area with a fixed-point mark in advance, the patrol device automatically collects the radio frequency signal sent by the fixed-point mark and contains a unique identification code, automatically records the time when the security patrol arrives at the location, and the data is sent to the computer online or afterwards. Because the remote data automatic collection technology is used to supervise the daily patrol work of security guards, it can effectively meet the complex requirements of patrol management work on the premise of ensuring the quality of patrolling. And because fixed-point marks can be arranged randomly according to needs, it effectively prevents cheating on mark points and ensures that there are no loopholes in monitoring.

The self-inspection patrol using RFID technology can also cooperate with other systems (such as CCTV monitoring) to monitor security patrols. On the one hand, it can ensure the personal safety of the patrol personnel, and on the other hand, it can also prevent the patrol personnel from not complying with the regulations.

The above is the application of RFID technology in the field of security. As a non-contact automatic identification technology, RFID has more advantages than traditional technologies, and there are more application scenarios waiting to be discovered. For many security companies, the application of RFID technology can further improve security capabilities, clear security blind spots, and fundamentally improve the core competitiveness of enterprises.
