Traditional public scale rental involves having an attendant in the scale house, especially in high-traffic areas like logistics parks where weighing volume is substantial, requiring scale operators to be on duty 24/7. This undoubtedly increases the workload of scale operators and raises personnel costs. To address this issue, our company has introduced high, medium, and low-end unmanned public scale self-service charging systems. These systems utilize 4G or network signal transmission with excellent waterproof performance. Drivers can independently scan codes to register weighing information, pay weighing fees, and print weighing slips. The entire process requires no manual intervention, and weighing profits are credited in real-time. Scale owners and drivers can view weighing orders and payment status, while the PC端 allows setting weighing fees. Operators, administrators, and financial personnel can be assigned different permissions for unified management.
