In recent years, for the problems that the public security department has previously faced with the problems of detailed supervision of physical evidence, damage and loss, which have led to the inability to solve cases or even appeal, the physical evidence management system is a sensor-based solution. Automatic inventory scanning and cataloging keep it away from paper records and manual entries, accurately manage various assets, and each asset contains an RFID chip, which helps the department better protect and deploy resources. Each piece of evidence is assigned a case number - multiple pieces of evidence can have the same number - and its own number. Unique identifier, passive UHF tags are attached to each piece of evidence, and the tags are in the physical evidence management system software, and the ID number is linked to the case and evidence number of the item.

The details of the physical evidence and the unique serial number of the RFID tag attached to it will be recorded in the database using the Zhenhe physical evidence management software application. Fixed RFID readers installed in different locations in law enforcement offices and courts will read each tag within the reading area of each reader antenna and create a record of the last known location of each item. For example, in the evidence room, each evidence table can also be equipped with a desktop or mobile handheld reader to record the location of the item. If an unauthorized person or the correct credential profile attempts to remove evidence, readers placed at the exit of the evidence room will ensure that unauthorized removal does not occur by initiating pre-selected security procedures such as sounding an alarm or locking the door and initiating an email or text message. Each tag's serial number will link to a database record for that item and can include all the details related to that item. In addition to enabling police departments to track the location of evidence, the system will track the custody of each item so that as items are transferred from police departments to forensic labs, district attorneys' offices and courts, a record is stored of every change to the possession and location of that item.

Wuxi Bosch Factory: RFID Technology Powered Fully Unmanned Smart Warehouse Case

Technologies such as RFID and AI facial recognition are now utilized for inventory management, replacing traditional manual registration processes. When requesting materials, staff simply scan a code to instantly locate the items. For returning surplus materials, employees can complete a self-service return through the system. This fully automated, intelligent process for both requisition and return makes the workflow highly convenient and efficient.

In the past, when we talked about RFID (Radio Frequency Identification), we mostly thought of the fixed turnstile at the warehouse entrance or the barcode scanner in the hands of the deliveryman. The inventory logic back then was very simple: the goods didn't move, but the people did, or the people walked around the goods with the equipment.

Stereoscopic warehouse RFID automated production line management

Visualization of the production line enables the enterprise management to discover the status of products in production and the operation of the production line in real time. The system mainly consists of assembly lines, RFID data collection systems, work-in-progress and workstations. Products in production move on the assembly line. When they arrive at the workstation, workers remove the recycled products for spare parts assembly. After completion, they are put back on the assembly line until all processes are completed.
