Admission managing system

An admission managing system for admitting a card holder of an integrated circuit card which has operating means, including a battery, for operating the integrated circuit card, means for receiving an external command to activate said operating means, a memory storing identification information, and means for at least communicating in a non-contact manner including reception of the command and transmission of the identification information, said admission managing system comprising:

• a gate admitting the card holder of the integrated circuit card when opened;
• first means for transmitting the external command to the integrated circuit card to activate said operating means and for receiving the identification information received from the integrated circuit card in response to the command;
• second means, coupled to said first means, for storing identification information of authorized card holders to be admitted;
• third means, coupled to said first and second means and to said gate, for comparing the identification information received from the integrated circuit card with identification information of each authorized card holder stored in said second means and opening said gate when the identification information received by said first means from the integrated circuit card is identical to one of the identification information stored in said second means;
• and
• fourth means, coupled to said first and third means, for determining number of times the same identification information is received by said third means from said first means and outputting a warning to the card holder if the number of times the same identification information is consecutively received by said first means from the integrated circuit card exceeds a predetermined value so as to avoid repeated transmission of the identification information from the integrated circuit card exceeding a certain time, so that an unnecessary power consumption of the battery of said operating means of the integrated circuit card is prevented.
