For controlling access to a sports facility, there is provided in addition to a user-carried non-transferable data storage medium (5) storing access privilege data to be read by reading means (2) on entry a data storage medium (6) disposed near the ground on the user's sports equipment, said data storage medium (6) storing control data to be read out by an antenna (3', 8) disposed near the ground at entrance (1) to the sports facility. The access privilege data read out from non-transferable data storage medium (5) upon entry are combined by program logic with the control data read out from near-ground data storage medium (6) on entry and then memorized. Upon each subsequent entry, the access privilege data and the control data are read out anew by antenna (3', 8) from non-transferable data storage medium (5) by reading means (2) and from near-ground data storage medium (6) by antenna (3', 8), respectively; entrance (1) is blocked in case of mismatch with the memorized combined data.
