PDA refers to a mobile data processing terminal with operating system (Android or WinCE), memory, CPU, graphics card, screen and keyboard, data transmission and processing capability, and battery. The function of PDA can be simply summarized as turning a tedious data list into a device that can be scanned, automatically matched and confirmed, which greatly improves the efficiency of item processing and turns the work of repeatedly checking and accepting data by operators into a simple work of scanning bar codes. Because it is automatic matching, the error rate is effectively reduced.
