4-3. Card Commands
(1) Card discharge command
This command discharges a card.
If there is a card in the device, this will discharge that card.
The card follows the discharge method specification parameter and is either discharged to a
position where it can be reused, or completely discharged.
Cards that are discharged to the reuse position and cards completely discharged are both set
to await being removed, and are not process targeted cards.
When a discharge command is issued to discharge a card discharged to the reuse position,
the card is completely discharged.

Parameter Explanation
• Discharge method specification parameter
‘0’: Discharge card to reuse position
Discharged cards wait to be pulled out and are no longer process target cards.
When either the command to take the discharged card into the device (the card rear side idle
command or the card front side idle command) or the removal wait status cancel command is
executed, the card becomes a process targeted card.
If there is a card waiting removal in the device, and the magnetic reading or printing command
is received, this card is not a process target card, so the card discharge process is executed
once to prompt the user to remove the card.
Note that once the card discharge command is applied to a card discharged to the reuse
position the card is completely discharged according to the discharge method that was
specified.
‘1’: Card is completely discharged.
Card waits to be pulled out and is not a process target card.
(2) Card front side idle command
This command transports and idles cards to the idling position on the front side.
Regardless of whether the card in the device is waiting to be removed or is a process targeted
card, it is transported to the idling position on the front side of the device and is idled there. If
there is no card in the device, the device waits until a card is inserted, then transports it to the
front side where it is idled. Idled cards are process targeted card.
If a card is not inserted after this command is issued, or to cancel the command, issue the
card insertion wait status cancel command (54h) after canceling the state of communication.
