Remarks
The data field is in the following format:
[
%
an-data
?
][
;
n-data
?
|
@
a-data
?
][(
+
n-data
?
|
#
an-data
?
|
!
an-data
?
|
&
an-data)]
an-data is alphanumeric data (ASCII characters ‘ ‘ to ‘_’ (0x20 to 0x7f))
n-data is numeric data (ASCII characters ‘0’ to ‘?’ (0x30 to 0x3f))
The data should not contain the end sentinel character (
?
).
If the application sends data for an alphanumeric track that contains lowercase
characters (ASCII values beyond 0x60), they will be capitalized if
capitalize
=
1
. To disable this and send the data as-is to the device, set the
capitalize
property
to
0
. The three sub-sections of the data string represent the three tracks on the
magnetic card. The data for each track begins with a start sentinel character, which
defines both the track number and the data format for the track:
%
identifies track 1 (7-bit alphanumeric)
;
identifies track 2 (5-bit numeric)
@
identifies track 2 (7-bit alphanumeric)
+
identifies track 3 (5-bit numeric)
!
identifies track 3 (CA Driver License)
#
identifies track 3 (alphanumeric, AAMVA)
&
identifies track 3 (7-bit alphanumeric)
Note that any or all of the data may be missing, but the order of the data for the
tracks must always be in order (1, 2, 3). A missing track is interpreted as “don’t
write” for the data encode command – that track will not be overwritten by the
encode operation.
The response sent for this command is:
/write
status.
status is
00
if the encode succeeded and non-zero if it failed.
See the definitions of the status values in Appendix C. Status Codes.
Example
Encode tracks 1 and 2:
Command
/write %B12345^TEST^0000?;12345?
<LF>
Response
/write
00
<LF>
