Abstract

An admission managing system manages admission of a card holder of an integrated circuit card which has a part for operating by a power induced by an external command, a memory for storing identification information and a part for at least communicating in a non-contact manner including reception of the command and transmission of the identification information. The admission managing system includes a gate for admitting the card holder of the integrated circuit card when opened, a first part for transmitting the command and for receiving the identification information received from the integrated circuit card in response to the command, a second part for storing identification information of authorized card holders to be admitted, a third part for opening the gate when the identification information received by the first part from the integrated circuit card is identical to one of the identification information stored in the second part, and a fourth part for outputting a warning to the card holder if a number of times the same identification information is received by the first part from the integrated circuit card exceeds a predetermined value.
