Keyboard Wedge Scanners |

|
The most popular interface for a barcode scanner is the "Keyboard Wedge". The scanner is physically wedged in between the keyboard and a terminal or PC with a "Y" cable. The advantage of the this connection is that the scanned data appears transparent to the keyboard. Data entry is independent of the application or operating system, so no unique software is required.
A keyboard wedge allows data scanned by a barcode reader to appear to the computer as though it were typed manually into the keyboard. Thus the use of a keyboard wedge streamlines the process of incorporating the use of a barcode scanner to an existing system.
