Bits Indicator Description
0 Front Card
Present
Set to 1 if a card is present anywhere in the front (insertion)
end of the card transport, or else cleared to 0. This bit can
be used to indicate the beginning of a card insertion or the
end of a card withdrawal. Note that once a standard sized
card is transported completely to the rear of the reader, this
indicator is no longer set.
1 Middle Card
Present
Set to 1 if a card is present anywhere in the middle of the
card transport, or else cleared to 0. This bit can be used to
indicate that a card is in a position from which it can be
ejected. If this bit is set, then a standard sized card should
be in contact with the transport rollers and thus be in a
position from which it can be ejected. Note that this bit is still
set once a standard sized card is transported completely to
the rear of the reader.
2 Rear Card Present Set to 1 if a card is present at the rear of the card transport
else cleared to 0. This bit can be used to indicate that the
transport has completely transported the card into the reader,
and that the card is in a position from which smart card
communications can occur.
3 Auto Transporting Set to 1 if the transport is transporting a card automatically,
or else cleared to 0. The transport is automatically
transporting when it transports a card due to an auto
transport property being set such as the Auto Consume
property. The Auto Transporting bit would not be set if the
transport is consuming a card in response to a consume card
command. This bit can be used to verify that the transport is
idle before taking action on the card position indicators.
4 Transport Cooling Set to 1 if the transport is cooling else cleared to 0. When
this bit is set, the transport will temporarily not be functional.
This cooling mechanism is to ensure that the transport is not
damaged by excessive stalling of the motor by the card user
or by the host software. A stall occurs when a card is held in
position while the transport tries to move the card. The
transport will give up trying to move the card in 0.5 to 2
seconds. If 2 stalls or blind ejects occur within a 5-second
period, then the transport goes into a cooling mode in which it
will not function for 5 seconds during which time this bit is set.

7 *MagnePrint Noise Set to 1 if the MagnePrint™ circuit is sensing excessive
electrical noise in the environment, else cleared to 0. If this
bit is set MagnePrint™ data may not be available. Moving
the reader away from noise sources (monitors, speakers,
etc.) may solve this problem. Note that the reader will not
check for noise until after a card swipe occurs. So a card has
to be swiped to initiate noise detection. If noise is detected
after the swipe, the reader will continue to check for noise
until the noise is no longer present. If no noise is detected
after the swipe, the reader will not check for noise again until
after the next swipe.
