The invention is a hand data collection terminal, comprising 
microprocessor, display module, 
infrared communication module, real-time 
clock, JTAG interface, reset circuit, memory, active oscillator, coulometric 
detector, keyboard 
detector, 
scanner interface, power supply module, 
buzzer, indicator light, backlight, photosensitive 
diode and extended 
system bus; it is integrated with a self-developed embedded operating systemí¬HQOS, ARM structured CPU hardware platform, 
laser scanning module, 
infrared communication module, etc. It reads bar code data by bar code 
scanner and then stores the bar code data, uses the 
infrared communication module to transmit the collected data to a user PC for storing a 
database. It can be widely applied to the bar code data collection for commercial retail, logistics and warehousing, 
medical treatment and health care, mobile meter reading and other mobile operations, etc.
