Bar code data collection, also known as inventory machines, handheld computers. It is the barcode scanning head or radio frequency tags (RFID) reader module with integrated data processing terminal with battery operated offline PDA Pocket PC. With real-time acquisition, automatic storage, real-time display, automatic processing, automatic transmission. Data collection can be divided into two, namely the batch data acquisition, wireless data collection or called RF handheld terminal.
Batch data acquisition using off-line work, batch data collection, through the USB cable or serial data cable to communicate with the computer. Each batch collector manufacturer independently developed embedded operating system, incompatible, because the data acquisition and computer via USB cable can only be connected to the lack of mobile real-time data processing capabilities, has fewer and fewer applications.
Wireless data logger built-in wireless communication module, through a wireless network (WIFI, GPRS, GPS or Bluetooth) real-time connection to the back-end application software database, real-time data updates. RF data collection is generally WinCE operating system or the Windows Mobile system, along with Google's Android open systems popular, there are many manufacturers of wireless barcode collector configuration of the Android system.
