<p>The invention relates to a double sided printable partially transparent and/or translucent base card (10) for application in a card operation device having an optical sensor, characterised by comprising a partially transparent and/or translucent card body (11), which card body (11) comprises at least one transparent and/or translucent core material layer (12) that has opposing face surfaces (22, 22a, 22b), and at least one face surface (22, 22a, 22b) of the at least one core material layer (12) is provided with a substantially non-transparent coating (20) at a detection region (18) of an optical sensor of at least one type of card operation device. The invention further relates to a method for manufacturing a double sided printable partially transparent and/or translucent base card (10) suitable for application in a card operation device having an optical sensor, characterised by defining the detection region (18) of the optical sensor of at least one type of card operation device on a transparent and/or translucent card body (11), which card body (11) comprises at least one transparent and/or translucent core material layer (12) that has opposing face surfaces (22, 22a, 22b), and applying a substantially non-transparent coating (20) on at least one face surface (22, 22a, 22b) of at least one core material layer at the defined location.</p> |
