Card Data - Elo TouchSystems Entuitive ET1725L Series User Manual

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. 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.
