<p>PURPOSE: To provide a mechanically readable coded strip for an identification card or the like without being easily forged or altered and damaged on its surface. CONSTITUTION: In the coded hologram strip 10 including plural hologram digits 30 linearly arrayed in a vertical direction so that eachhologram digit 30 includes at least one parallel stripe reflection hologram, each parallel stripe reflection hologram is constituted so as to diffract reproduced light having prescribed wavelength and an incident angle by a diffraction angle substantially equal to a reproduced incident angle.</p> |
