A start-up power is generated in the chip 110, a circuit inside the security chip 110 starts, and the security chip 110 starts communication with the RF reader / writer 130. The power required for driving the security chip 110 is supplied to the RF interface 112 through the chip antenna 111 as an RF signal. This electromotive force uses the principle of electromagnetic induction. According to this method, the security chip 110 can semi-permanently communicate with the RF reader / writer 130 in a non-contact manner without incorporating the power required for driving.
This method is well known in the field of non-contact type IC cards.

When the security chip 110 is activated, the security chip 110 transfers the password stored in the memory 115 to the RF interface 112 via the serial interface 113. The RF interface 112 transmits the RF signal obtained by modulating the password to the RF reader / writer 130 via the chip antenna 111.
