Abstract

For anbringelse av en sikkerhetskode på en artikkel, så som et sjekkgaranti- kort, et kredittkort, et identitetskort eller en komponent av en motor eller maskin, gjøres det bruk av et hologram eller kinegram (2) i hvilket personifi- serings- eller identifiseringssymboler, bokstaver, tall eller figurer er eller vil bli utskåret ved innbrenning ved benyttelse av en laserstråle, idet holo- grammet eller kinegrammet festes til et underliggende hologram eller kinegram som er festet til artikkelen direkte eller via ett eller flere hologrammer eller kinegrammer, idet de forskjellige særtrekk er slik at den optiske virkning' av et underliggende hologram eller kine- gram er synlig gjennom de utskårne sym- boler (4).
