Abstract
A method of controlling an electronic circuit is provided. A command is received from a control unit. The command is interpreted in either a first manner if the command is followed by a predetermined dead time, or a second manner if a new command is transmitted before expiration of the predetermined dead time. In a preferred embodiment, the command is interpreted in the second manner only if the new command is identical to the command. Also provided is a chip card that includes an antenna, at least one memory, and a control circuit. When a command is received, the control circuit performs either a first function if the command is followed by a predetermined dead time, or a second function if a new command is transmitted before expiration of the predetermined dead time. Additionally, a telephone apparatus is provided that includes a read/write device for contactless control of a chip card. The read/write device includes an antenna and a control circuit. When a command is transmitted, the control circuit either allows a predetermined dead time to pass to instruct the chip card to perform a first function, or transmits a new command before expiration of the predetermined dead time to instruct the chip card to perform a second function.
