As the core measuring equipment in logistics, mines and ports, weighbridges undertake key tasks such as truck load settlement and raw material inventory management. Traditional manual records are prone to data tampering (±5% error), vehicle queue congestion (average waiting time of 30 minutes/vehicle) and cheating risks (such as incomplete weighing and repeated weighing). The introduction of long-distance barcode reading modules, by automatically collecting vehicle/cargo IDs and binding them with weight data, builds a tamper-proof and trusted data chain, and becomes a core component of the industry's digital transformation. Choosing a suitable long-distance barcode reading module in the weighbridge industry is a problem we need to consider.
