A basic sheet or lamina (1) of the card receives micro-film or micro print data or information (3) printed or applied on a face area (10 or 11) of the sheet (1). The data (3) is such that it cannot normally be ascertained by the naked eye but on insertion of that part of the card bearing the data (3) into a suitable reader or projector the data can be viewed on an enlarged scale. The face area may provide a transparent window (10) for enlarged scale viewing of the data (3) thereon by light passing through it or the face area (11) may receive the data (3) for enlarged scale viewing by reflected light in a reader or projector. The data (3) may include in particular a photograph of the face of the authorised holder of the card together with other personal details, bank account number etc. and preferably medical information. <IMAGE> |
