Here I briefly introduce my familiar data collector for bar code acquisition.
Data collector, also known as PDA handheld terminal, inventory machine, bar code data collector, etc. , is an intelligent terminal device integrating bar code scanning equipment, RFID technology and data terminal, and has a battery that can run offline. It has the functions of real-time acquisition, automatic storage, real-time display, real-time feedback, automatic processing and automatic transmission.
