PS2 Barcode Scanners, also known as Keyboard Wedge, allows a user to scan data and have it appear on a computer screen just as it would had it been typed through a keyboard. A Keyboard Wedge Barcode Scanner connects through the keyboard port of a computer (see image to right). The limitations to PS2 Barcode Scanners are that barcode data cannot be modified prior to displaying on the computer screen. Just like other barcode scanners, Keyboard Wedge Barcode Scanners are offered in 1D and 2D. Check out our selection below.
