Abstract

A passage control device for non-contacting data carriers has an antenna unit (5) with a front wall (12) extending in the passage direction and facing the passageway, the height of said wall corresponding to the different wearing heights of the data carriers, and said wall having disposed thereon at least one antenna (13, 14) for data transmission in the radio wave range, and a turnstile (4) with an obliquely downward pointing hinge pin (8) and barrier arms (10) extending obliquely to said hinge pin. The front wall (12) of the antenna unit (5) extends downward beyond the bearing of the turnstile (4). The turnstile (4) is mounted on the area of the antenna unit (5) on the front in the passage direction (15), and the portion (17) of the front wall (12) extending downward beyond the turnstile bearing extends obliquely rearward. The front wall (12) of the antenna unit (5) is designed as an information surface (18) for optical information.
