CARD DATA (HID)

The details about how the card data and commands are structured into HID reports follow later in

this section. Windows applications that communicate to this device can be easily developed.

These applications can communicate to the device using standard windows API calls that

communicate to the device using the standard Windows USB HID driver. These applications

can be easily developed using compilers such as Microsoft’s Visual Basic or Visual C++. A

demonstration program and its source code, written in Visual Basic, that communicates with this

device is available. This demo program can be used to test the device and it can be used as a

guide for developing other applications. More details about the demo program follow later in

this document.

It is recommended that application software developers become familiar with the HID

specification the USB specification before attempting to communicate with this device. This

document assumes that the reader is familiar with these specifications. These specifications can

be downloaded free from www.usb.org

Card data is only sent to the host on the Interrupt In pipe using an Input Report. The device will

send only one Input Report per card swipe. If the host requests data from the device when no

data is available, the device will send a NAK to the host to indicate that it has nothing to send.

When a card is swiped, the Input Report will be sent even if the data is not decodable. The

following table shows how the input report is structured.
