A non-contact integrated card includes a data transmitting and receiving circuit, a data processing unit connected with the data transmitting and receiving circuit, a clock generating circuit for generating a clock signal and for supplying the clock signal to the data processing unit, a battery for supplying electrical energy to the data transmitting and receiving circuit, the data processing unit and the clock generating circuit, and a clock stopping circuit for stopping the generation of the clock signal by the clock generating circuit upon receipt of a clock stop signal from outside of the card. The inclusion of the clock stopping circuit which stops the generation of the clock signal in response to a clock stop signal input from an external circuit makes it possible to suspend the consumption of energy produced by the battery after testing, during shipping, and before use of the card.
