Access control system

A system for controlling access of a person to an area comprising:

• a portable access authorization data carrier for mounting to an object for carrying by a user and for receiving and storing an access authorization;
• an access control apparatus for controlling access of a person to an area comprising an access authorization reading device including an antenna disposed in a ground area for reading an access authorization from said portable access authorization data carrier;
• an evaluation unit for evaluating the access authorization from the access authorization reading device to provide access for a person to the area when the access authorization is received;
• a portable copy-over data carrier on which a coding authorization and an access authorization are stored upon acquisition;
• a copy-over reading device for reading the coding authorization and the access authorization from the portable copy-over data carrier;
• and
• a coding device including the antenna of said access control apparatus for coding the access authorization received from the copy-over reading device onto the portable access authorization data carrier during a first pass of the portable access authorization data carrier through the ground area of the antenna, the coding device deleting the coding authorization in the portable copy-over data carrier after the copy-over reading device reads the coding authorization,
• wherein the access control apparatus repeatedly provides access for a person to the area in response to each subsequent detection of the access authorization stored on the portable access authorization data carrier.

A system for controlling access to an area comprising:

• an access control device including a singling device;
• a portable access authorization data carrier for mounting to an object for carrying by a user near the ground and for receiving and storing an access authorization;
• a portable copyover data carrier separate from said portable access authorization data carrier, on which a coding authorization and an access authorization are stored upon acquisition;
• and
• a reading and coding device for 1) reading the coding authorization and the access authorization from the portable copy-over data carrier;
• 2) sending the access authorization read from the portable copy-over data carrier to said portable access authorization data carrier for storage therein;
• and 3) deleting the coding authorization on said portable copy-over data carrier,
• wherein said reading and coding device enables access through the singling device each time a valid access authorization from said portable access authorization data carrier is detected.

A method for controlling access of a person to an area comprising:

• providing a copy-over data carrier coding device;
• storing a coding authorization and an access authorization in a portable copy-over data carrier with the copy-over data carrier coding device;
• providing the portable copy-over data carrier and providing a portable access authorization data carrier to a person at a first location;
• providing an access control apparatus having a non-contact-type access authorization reading device disposed at a second location a distance from the first location;
• providing a copy-over reading device and an access authorization data carrier coding device at the second location;
• reading the coding authorization from the portable copy-over data carrier with the copy-over reading device at the second location;
• reading the access authorization from the portable copy-over data carrier with the copy-over reading device at the second location;
• in response to the coding authorization as read by the copy-over reading device, coding the access authorization onto the portable access authorization data carrier with the access authorization data carrier coding device to store the access authorization in the portable access authorization data carrier;
• deleting the coding authorization from the portable copy-over data carrier so that the portable copy-over data carrier is usable only once for providing the access authorization to the portable access authorization data carrier;
• detecting a valid access authorization from the presence of the portable access authorization data carrier, with the non-contact type access authorization reading device;
• and
• repeatedly enabling access to the area for a person by operating the access control apparatus in response to the non-contact type access authorization reading device detecting a valid access authorization on the portable access authorization data carrier.
