RFID has developed rapidly in recent years. Government agencies of various countries have continuously increased their application efforts. Major well-known manufacturers have continuously introduced innovative products. Researchers from various parties have continuously proposed new ideas. The following is a collection of successful application cases of foreign RFID in the police field in recent years. Most of these cases have also been widely used in my country.
1. The British police use RFID-based iDAS to protect gun safety
Two companies, TAGSYS and RFIP, announced that they have designed a new RFID-based weapon tracking solution-the “Intelligent Drawer Armament System” (iDAS). The purpose of this program is to protect the weapon safety of the army and law enforcement agencies. iDAS uses embedded RFID technology to automatically record the issuance and return of weapons in storage cabinets, prevent weapons from being issued to unauthorized police officers, and generate audit reports and submit them to supervisors, thereby improving the safety of weapons.
At present, some police stations in the UK have adopted iDAS, using storage cabinets equipped with RFID to track Taser guns. They attached a high-frequency TAGSYSArio370-SDMRFID tag to the Taser gun body and monitored it through the TAGSYSMedioP032OEMRFID reader and the antenna in the storage cabinet.
David Armstrong of RFIP said: “TAGSYSArio370-SDMRFID tags are very small, they can be easily attached to the Taser gun, under the premise of ensuring a reliable identification range, will not affect our use of the gun. In addition, these tags are very strong and durable. , Not easy to fall off.”
Prior to this, Taser guns were originally issued by higher-level British police stations, but now such guns are deployed in lower-level police stations. Therefore, local police stations need a safe, simple, and economical way to deal with them. It is managed.
The main workflow of iDAS is: when a police officer needs to receive a Taser gun, he should first submit his ID card to the card reader in the storage cabinet; then, the iDAS system will determine whether the officer has obtained a legal gun permit If the result of the judgment is “yes”, the touch screen that comes with the iDAS system will guide the police officer through a series of legal and procedural precautions; then, the iDAS system will automatically pass the asset management application (developed by JMLSoftwareSolutions) Assign a certain Taser gun to the police officer, order the drawer to open the drawer where the gun is stored, and electronically register the Taser gun; finally, the police officer can take the gun away, as shown in Figure 1.

The iDAS system not only allows managers to know which police officer took which Taser gun, but also provides an audit trail report to the police department to investigate incidents involving the use of Taser guns or related police officer training records.
2. The use of RFID/GPS to manage police in the UK caused controversy
According to the well-known British publication “Police Review”, the Metropolitan Police Agency of Greater London plans to use the Automatic Personnel Positioning System (APLS) to replace the Airwave wireless system currently in use in order to better manage the 31,000 police officers in its jurisdiction. As shown in Figure 2.
Figure 2 British police use RFID/GPS to manage police
According to Telent, the provider of this technology, APLS is one of the largest similar systems in the world. It places RFID microchips on police officers and uses GPS to accurately locate police officers (within a few feet), enabling management The staff of the center can “know where any police officer is on duty at any time, no matter if he is on the ground or underground.” In this way, the police can dispatch the nearest police officer to the scene of the incident to handle related affairs, thereby achieving more effective and efficient operations. Swift police delivery. In addition, if a police officer is injured or kidnapped, his location can be known through the system, which is conducive to launching more effective rescue operations, thereby improving the personal safety of the police. Therefore, APLS can become a very useful police service. Management tools.
Although police chiefs expressed their praise for this new technology, some police officers expressed concern. First of all, the system may force the police to follow the orders of the management center, and is not inclined to respond to other police officers on the scene, thus having a negative impact on the community policing mechanism; secondly, it may infringe on the police’s privacy. For example, how long the police spent in the bathroom, how long they spent talking with others, etc. will be known to the management; again, criminals may illegally access this RFID network, once they know the number of police officers in a certain block and where they are In specific locations, they can try to avoid direct conflicts with the police. In addition, they may also identify undercover police agents through the system (because these people have RFID tags hidden on their bodies), and copy and imitate RFID devices. To mislead the system management center and make managers misjudge the actual number and location of police officers. At present, the controversy about this technology continues.
3. The Santa Clara County Crime Laboratory uses RFID to track evidence
In the process of dealing with criminal incidents, the role of evidence is extremely critical. It sometimes even determines whether a case can be successfully solved. Therefore, reasonable management and tracking of evidence is a very important issue.
The SantaClara County Crime Laboratory in the United States and the system integration company CIBER International have developed a complete integrated solution, which includes a set of RFID evidence tracking system. The system uses the RFID solution derived from AlienTechnology®, which can keep track and monitoring of the evidence during the process of criminology experts or other staff taking the evidence out of the locker and carrying it to various testing laboratories.
Laboratory director DelRe said: “We want to use a new and efficient way to track the movement of evidence in the building, because we want to know where a certain piece of evidence is at a certain time, and also want to understand this piece of evidence. Who is assigned to use it. We are the first laboratory in the United States to use RFID technology to track evidence.”
After using the RFID system, this laboratory can track the movement of all evidence through a complete evaluation cycle. First, law enforcement officers bring the evidence into the laboratory and enter the evidence in the crime database through a network-based system. Subsequently, DelRe’s team will attach an AlienRFIDSquiggle? tag and barcode (this barcode is a backup system for RFID) to the evidence, and then send it to the storage room on the first floor. With these two technologies, the laboratory can guarantee 100% accurate tracking of evidence.
The laboratory uses two different sizes of RFID tags, one is smaller, used for evidence such as blood sampling bottles; the other is standard, used for all other evidence. These labels can be affixed to various exhibits (such as plastic bags containing trace evidence, blood sampling bottle trays, and even cars), and can withstand temperatures below freezing during refrigeration.
Currently, there are 7 AlienRFID9650 readers in the laboratory building. They are located at checkpoints on each floor. Some of these checkpoints are in the storage room or near the elevator. The staff and evidence technicians first confirm the list of evidence at the checkpoint, then transfer the evidence to the laboratory and return it to the storage room after the test. Throughout the process, the RFID tracking system reads the identification information and confirms the time of leaving and returning to the exhibit storage room. By using RFID to monitor the “evidence chain”, the laboratory has improved the efficiency and quality of evidence tracking.
With the development of RFID technology, various law enforcement agencies will be able to access the evidence database, allowing the interconnection of evidence in different public security jurisdictions, which will greatly promote the entire public security business.
4. The Australian government adopts the RFID program of American HID to manage weapons
Australian Customs and Border Protection announced that it will use HID’s RFID technology to track its weapons and personal protective equipment warehouses in real time.
With the use of the new weapons inventory management system, the Australian Customs and Border Protection currently needs to manage about 6,000 weapons and personal protective equipment, which are located in multiple arsenals. It is reported that HID’s RFID technology has previously been used by the Australian Customs in the weapons inventory management system. The Relegen solution in this system combines next-generation software and smart multi-layer tags. Among them, the asset tag component of the Relegen solution uses HID. LogiTag and INTag solutions, as well as DataTraceDNA security technology from Australia’s DataDot.
In addition to providing weapons and personal protective equipment tracking services, the new Relegen program can better protect the personal safety of law enforcement personnel, improve the security of item distribution and retrieval, and improve the efficiency of item management. The security features of the program ensure that items are only distributed to law enforcement personnel who are qualified to use it.
5. Indian researchers intend to develop RFID devices to prevent the use of mobile phones while driving
Researchers from Anna University in India wrote an article that they plan to develop an RFID device to prevent drivers from using their mobile phones while driving.
According to the article published in the “Journal of International Business Management”, this device will use RFID technology to automatically detect whether a vehicle is driving and whether the driver is trying to use a mobile phone. Once discovered, the device will trigger a mobile blocking signal, and this signal will only affect the driver and not the passengers.
Previously, similar technologies were used to prevent drivers from using their mobile phones while driving. The SafeTexting application on Android phones can prevent drivers from sending and receiving text messages, but it can also affect passengers. In addition, other devices use the horn in the car to generate a buzzing sound. If the driver dials the mobile phone while driving, the mobile phone will detect this sound and achieve the purpose of blocking it.
The device to be developed by Anna University can automatically detect the mobile phone signal of the driver and actively block the information transmission of his mobile phone. In addition, this device can also be connected to local law enforcement agencies. When it detects that the driver is using a mobile phone, it can automatically send the data stored in the RFID tag of the license plate to the police for further processing.
6. Canadian Terepac company releases miniature short-range RFID tags
Terepac, located in Waterloo, Ontario, Canada, is the world’s leader in micro digital electronic technology. The company released a short-range wireless communication technology RFID tag-TereTag, which can enable almost all objects to join the Internet of Things.
This kind of label is silently implanted in the host, but it brings a series of enhancements to the ability, making it more convenient and safe for users to identify, communicate and operate.
At the Waterloo product launch, Terepac CEO RicAsselstine said to the company’s shareholders and employees: “We can apply electronic technology to areas that have never been imagined before. Such products will be lighter in weight and smaller in size. , The price is lower, and the harm to the environment will be less.”
The tiny device displayed at Terepac’s shareholder and employee meetings can be embedded in a company-specific logo on a hat or coaster. Simply tap on Teretag with your mobile phone to enable tag owners to share information related to the logo via Twitter, Facebook, Google, etc. Users can access the detailed information of the product and share it with friends through social networks. RicAsselstine added: “We have always been facing the need to not only make micro electronic devices for an object, but also to connect it to other devices through the network. This requires the creation of related applications so that the object can become itself An application platform that can mine and manage data generated by objects, and visualize the data. Finally, the platform realizes social media connections and provides a one-stop service for the expression of objects.”
Terepac has a patent protection program that allows the company to make circuits to an unprecedented level. This passive 13.56 MHz tag is designed using the company’s patented assembly method. It is smaller and cheaper than other NFC tags on the market.
7. German designers design bicycle RFID alarms
A German designer named DennisSiegel recently designed a radio frequency identification alarm (RFIDBikealarm) that users can install under the bicycle seat. When it detects movement when it is unlocked, it will emit 120. The decibel siren is enough to scare thieves. RFID Bikealarm is a very useful additional car lock assembly. It uses a few components to expand a large-scale protection mechanism. It has the characteristics of low cost, sturdiness and easy operation, as shown in Figure 3.
Figure 3 RFIDBikealarm
According to Dennis Siegel, he used a micro-power omni-directional vibration sensor in the production process, which can be connected to a microcontroller. RFID Bikealarm recognizes specific events through its perception of the surrounding environment, such as a passing tram and a real theft.
The designer added an alarm mode to RFIDBikealarm, which can make a sound during movement. The reason why I chose to install the device under the saddle of the bicycle is that the location is relatively concealed and looks like a small repair kit.
Dennis Siegel abandoned wireless Bluetooth technology and adopted RFID radio frequency identification technology, mainly because of the cost. A user holding an RFID tag can activate it by approaching the device until the audio transponder emits a sound, and the way to turn it off is the same.
RFIDBikealarm uses a built-in battery design, which can be charged through the USB interface, and it can be fully charged in two hours, and it can be used for several days under normal conditions.
