Laser Decode Zone
The decode zones for the Class 1 and Class 2 lasers in the CF RFID Reader-
Scan Card are shown below. The minimum element width (“X Dimension”
or bar code “size”) is the width in thousandths of an inch (mils) of the
narrowest element (bar or space) in the symbol. The figures shown are the
typical scanning distances (depths of field) for selected bar code sizes. The
maximum usable length of a bar code symbol (Width of Field) at any given
