Data Header
If YES is selected, a single character header precedes the data. For MICR data, the message is
transmitted as follows:
MICR data: ‘C’[data]
For card data, the header position on the message is controlled by the Card Data Message
parameter (see below). Therefore, the message may be transmitted as follows:
If Multiple Message: ‘M’[TK1]‘M’[TK2]’M’[TK3]
If Single Message: ‘M’[TK1] [TK2] [TK3]
It is important to note that the Data Header precedes the data and not the message. For example, if
, and Data Header are set to YES, a MICR data message will be transmitted as
follows:
MICR data: ‘C’[data]
Card Data Message
This option determines the structure of the output message for the individual tracks when a credit
card is read. If Multiple is selected, the Control Characters (see SWB, below) and Data Header
(see Data Header, above) are added to each track individually. On the other hand, if Single is
selected, all available tracks are lumped together into a single message. For example, if ,
and Data Header are set to YES, the output message may be transmitted as follows:
If Multiple Message: ‘M’[TK1]‘M’[TK2]‘M’[TK3]
If Single Message: ‘M’[TK1] [TK2] [TK3]
