VersaKey with USB-HID Reader Interface
1.0
Introduction
The scope of this document pertains specifically to USB VersaKey keyboards with
MagStripe readers, where the keyboard & reader USB interfaces are of two different
device classes. The keyboard interface is a typical USB Keyboard; the MagStripe
reader interface is USB-HID. The data transmitted for both is over the single
keyboard communication cable.
This document provides two sections of information. The first section is general
information of the USB interfaces, the reader, and its operation in the VersaKey
keyboard. The second section provides technical information for the reader USB-
HID interface. The second section is typically for applications programmers needing
information to develop software applications.
A demo program with its source code is available, written in Visual Basic, and
operates with the reader using the standard Windows HID API. Visit the ID TECH

The HID interface, General Information
Some VersaKey product models provide an integral MagStripe reader having a
USB-HID communication interface. The reader is a "vendor defined HID device"
so that a direct communication path can be established with an application.
The reader conforms to the USB Human Interface Device (HID) Class
specification Version 2.0. Host applications designed for the latest versions of
Windows 98, Me, 2000, XP can easily communicate to the reader using standard
Windows API calls.
The reader conforms to ISO/IEC 7811 standards. The reader is compatible with
personal computers or device with a USB interface.

Installation
There are two separate USB communications interfaces using the single
keyboard communication cable. Connect the VersaKey USB cable to a host
USB port. The keyboard interface is "plug-n-play" and the keyboard functions
immediately after the cable is connected. The reader has an independent USB-
HID communication interface; some set-up may be required.
