Pass 85 was first introduced on 1 April 1985. Its data page was not machine readable. The medium-red cover is decorated with a large Swiss cross and the words "Swiss Passport" vertically in 5 languages. An earlier version of Pass 85 only had 4 languages, until Romansh was made a national language in Switzerland in the late 1980s. Safety features include UV-reactive paper, watermarks with the page number and Swiss cross, Guilloché printing with variegated colours, colour shift ink, and printing registration elements when the passport is held up to light. The photograph of the bearer was glued on and embossed with two seals. Black and white photographs were acceptable in Pass 85. As in older passport versions, the bearer's hair and eye colours were stated.
