(D)
NOTE: 1. The DFn field must be defined previously in the CREATE mode before it can be specified in the
VERIFY command otherwise it will be considered as a syntax error and the VERIFY command
will abort.
2. All RFID Read/Write commands are executed first in the order they appear in CREATE mode,
followed by Alpha and Barcode commands, and finally VERIFY commands. The VERIFY
commands are always executed last although they may appear before other commands in the
CREATE mode. The reason for this is to make sure the data are sent back to the host only if
other commands are completed and the form is not aborted.
3. If the data comes from a DFn field, the DFn format is the original format before any conversion.
If the VERIFY command specifies a different format, the data would then be converted to the
new format. If the data comes from an AFn or BFn, the original format is S format.
4. Below is the possible syntax for header and trailer string,
1, VERIFY;DF2;H;*Head = *
2, VERIFY;DF2;H;*Head = *; *Tail* //Header & trailer
3, VERIFY;DF2;H;**;*Tail*
4, VERIFY;DF2;H;*Head = *;**
To insert the CR/LF character, add "\r" and "\n" as CR/LF characters, such as
VERIFY;DF2;H;*Head=*; *Tail\r\n* //this will display "Head=<tag data>Tail<CR><LF>"
If the user wants to display "\r" or "\n" as normal text character, do the following:
VERIFY;DF2;H;*Header\\r\\n*
The characters \r and \n can be inserted anywhere in the header string and trailer string.
To summarize,
\r –> 0x0D
\n –> 0x0A
\\ –> \
Example 1
This example requests the printer to send to the host the content of the RFID tag, in hexadecimal format,
both before and after the RFWTAG command writes data to the tag. Also, the label is not moved.

A mandatory parameter to specify an ASCII string of characters, which is
followed by the RFID data, to be sent by the printer to the host.
An optional parameter to specify an ASCII string of characters, which
will follow the RFID data, to be sent by the printer to the host.
Delimiter designating the start and end of a character string. Replace
(D) with any printable character, except the SFCC and the slash
character (/). The string could be empty, i.e. there are not headers
preceding the field data.
//Header only
//Trailer only
//Header only
//this will display "Header\r\n" on the screen, where
double back slash "\\" (0x5C 0x5C) will be replaced with
one back slash '\' (0x5C).
//CR
//LF
//one back slash
