Defining the RFID Data Field 4-5
Using Option 30 (Pad Data)
You can add characters to one side of a field to "pad" the field. Padding
allows you to fill in the remaining spaces when the entered data does not
fill an entire field.
If a variable length field is not completely filled with batch data, this
option fills the remaining positions in the field with the character
designated by Option 30.
