Security features present on Nepali passport are examined with the help of Video Spectral Comparator. Mainly examination is carried out with application ultra-violet light, normal light, oblique light and transmitted light. We obtain different types of security features including florescence, ghost image, binding thread, optical fiber, punched number, barcode, micro-printing, watermark, emboss etc.
