Detailed Description of USB Barcode Scanner Application Integration Guide 2006

This guide provides software, documentation, examples and VB6 source code for the integration of hand-held USB and keyboard emulation barcode scanners. Using these guidelines, hand held scanners may be easily integrated with existing or custom applications as input, automation and verification devices. Documentation is provided in the ReadMe.html file.

RS232 (serial port) barcode scanners have been commonly used as input devices for several decades. RS232 scanners work very well in their legacy applications, although their implementation is complex because it requires that the application monitor and access the RS-232 API. In addition, some new computer systems on the market today do not contain RS232 ports and the serial port is a slow communication device.

USB and keyboard wedge barcode scanners overcome these limitations by emulating the keyboard so that anything scanned appears at the cursor as if it had been typed in from the keyboard. The guidelines presented here offer several implementation options.
