Problems solved by technology

The current inventory system is mainly for hand-held RFID terminal equipment inventory, which is inefficient and error-prone

Items in the warehouse sometimes need to come in and out frequently, and may also need to be searched irregularly. If you enter the location of the goods one by one when they are put on the shelf, it will take a lot of manpower, and it is easy to cause human errors such as missing items and incorrect input of item information. And if there is a change in location and the information needs to be re-entered, it will consume a lot of manpower
