Technical Field
In inventory management, inventory is a very important link. The traditional manual inventory has low efficiency and high error rate, and cannot meet the requirement of large-scale warehouse inventory management at all. The inventory mode is gradually changed from a manual mode to an automatic inventory mode by applying RFID scanning equipment.
the existing inventory methods using RFID devices generally have two types: one is that a hand-held scanning device is used for scanning goods and checking, namely the goods are not moved; the other method is to carry goods into a scanning device by manpower or a forklift for checking, namely manual goods movement. In any mode, manual participation is not needed, manpower is consumed, and the accuracy of checking is influenced.
