Cards for Processing
The cards that can be processed are called readable and writable cards.
When the card is inserted into the inlet, it is a process targeted card.
When the process is completed, the card idles in the machine, and is a process targeted card.
When idling in the device, the idling card is a process targeted card regardless of whether
there is a card at the inlet.
Cards discharged from the device are removal waiting cards and are no longer process
target cards.
To process these cards, they must be removed from the device once, and then reinserted, or
they can be processed by employing the removal wait cancel command (55h).

Retrying and Verifying
The visual card reader/writer will retry to read or to write to a card when it fails to read or write
data to the magnetic stripe. (This is when a retry count is set.)
When the set number of failures to read or to write is reached, reading or writing is canceled.
The device rereads the magnetic stripe after writing thereto. If the data that it reads does not
match the data that was written, it detects a writing error.
This reading of the data is called 'verifying' and is performed automatically.
The default value for retries is set to two times (total of three).
