Read Arguments

The optional argument x used in the read command specifies the type of data to read and y specifies the text to be displayed. The following table describes the recognized x arguments for the read command:

Read	Description
Argument
any	Read any type of data.
	This option is equivalent to read without any arguments.
card	Read magnetic stripe card. Display message (msg 1) if defined.
	When the user swipes a card, the response will be in the following format:
	/read MX1X2X3SS data
	XI define the track read status for each of the three tracks, as follows:
	0 = good track
	1 = bad track
	9 = no track data.
	SS is a two-digit status code; it is not affected by errors reported in the
	Xi field:
	00 – successful read
	82 – canceled, etc.
	data is the card data for all successfully read tracks.
card_w_pin	Read magnetic stripe card and collect PIN from cardholder. Display
	messages if defined.
	This command is similar to the read card command except that after the
	card is swiped, the device collects and stores the cardholder’s PIN. The
	PIN can be collected later by issuing the read pin command.
	Before issuing this command, the following properties may be set:
	msg1, msg2, msg3 – messages to be displayed while waiting for card
	swipe and PIN entry (a default message will be used if these properties
	contain empty strings).
	The response to this command is identical to the read card response; if
	successful, it returns the track data from the magnetic card. If the response
	status SS is 00, the read pin command can be used to collect the PIN.
check	Read check data.
	When the user reads a check, the response will be in the following format:
	/read CX1X2X3SS data
	XXX is the decimal representation of the check read status, as defined in
	the MICR specification, e.g., 004 indicates a bad character in the
	check number field.
	SS is a two-digit status code: 00 – successful read, 82 – canceled, etc.
	This status is not affected by errors reported in the XXX field.
	data is the check data, which is also available in chk_data. The data
	format depends on the setting of the chk_format property.
