Abstract
A wireless card, in response to a synchronization signal received from a gate machine, transmits a user information to the gate machine. The gate machine examines whether the wireless card is available using the user information. Necessary information obtained based on the user information is retained in the wireless card when it passes through the gate. A user can be informed of the necessary information at any desired time after passing through the gate. The necessary information is generated in the wireless card and/or in the gate machine. The necessary information obtained in the gate machine is transmitted from the gate machine to the wireless card.
