CARD DATA
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. The MSR direction property, defined later in this
section, determines the direction of the card swipe that will generate an Input Report. This
property can be set to insert, withdrawal or both. 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.
