QR-kodstandard, ISO\/IEC 18004, antar m\u00f6rka moduler p\u00e5 en ljus bakgrund. M\u00f6rka moduler absorberar ljus och den ljusa bakgrunden reflekterar det. Om skillnaden \u00e4r f\u00f6r liten kan avkodaren inte separera datam\u00f6nstret fr\u00e5n bakgrunden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vid streckkodstestning (ISO\/IEC 15415) \u00e4r symbolkontrasten skillnaden mellan den ljusaste och m\u00f6rkaste reflektansen i koden. En symbolkontrast p\u00e5 70 % eller mer ger h\u00f6gsta betyg, och under 20 % misslyckas. Granskare kontrollerar ocks\u00e5 modulation, vilket visar hur j\u00e4mnt de ljusa och m\u00f6rka modulerna reflekterar \u00f6ver hela symbolen. Oj\u00e4mna f\u00e4rger eller svag separation g\u00f6r att skannern missar modulkanterna.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Normal polaritet, med m\u00f6rka moduler p\u00e5 en ljus bakgrund, fungerar p\u00e5 alla enheter. Vissa inbyggda kameraappar i telefoner kan inte l\u00e4sa ljusa koder p\u00e5 m\u00f6rka bakgrunder, och st\u00f6det skiljer sig \u00e5t beroende p\u00e5 telefonmodell och programvaruversion.
