Writing a Kill Code and User Data
Kill codes and user data can be written to any tag in the field in the same manner as
the EPC code method described above, but typically a kill code and user data
would be associated with a specific EPC code. Once written, you cannot read back
the kill code.
To write a Kill Code, enter the following:
}Wa,a:0,b:112233,l:3!
To write User Data to any tag, enter the following:
}Wa,a:3,b:00112233445566778899aabbcc,l:d!
To write a specific tag, enter the EPC code and the 16-bit CRC. The following
write command singulates using ID2, so PE0 singulation bits are ignored:
}Wt,a:0,d:220000000000000000000003DCD0,b:112233,l:3
!
To write user data to any tag: (singulates using ID2, so PE0 singulation bits
ignored)
}Wt,a:3,d:220000000000000000000003DCD0,
b:00112233445566778899aabbcc,l:d!
