Claim 7:
8. A room access arrangement having first and second revolving doors, each comprising
a rotatable door leaf element which has at least three door leaves which are fitted to a vertical centre axle,
at least one part-circular wall portion which is arranged adjacent to the rotation circle of the door leaf element,
sealing elements for electromagnetic shielding arranged in the transition between the at least three door leaves and the respective at least one partly circular wall portion,
an electronic reading unit adapted for wireless reading of data from transponders,
wherein the electronic reading unit is orientated towards a reading space, said reading space being delimited by the wall portion and a pair of door leaves of the at least three door leaves when the revolving door is in a reading position, and
a predetermined entry side and a predetermined exit side,
wherein each of the first and second revolving doors is constructed to permit passage from the entry side to the exit side and to prevent passage from the exit side to the entry side,
wherein the wall portion which delimits the reading space overlaps in the reading position of the revolving door the pair of door leaves of the at least three door leaves which form a passage space in order to electromagnetically shield by contribution of the door leaf element and the wall portion which overlaps the door leaf of the reading space when the revolving door is in the reading position,
wherein the first revolving door is arranged with the exit side thereof in an inner space which can be accessed through the first and second revolving doors,
wherein the second revolving door is arranged with the entry side thereof in the inner space, and
wherein access to the inner space is carried out via the first revolving door and leaving the inner space is carried out via the second revolving door.
