Abstract

PURPOSE:To provide the personal communication terminal equipment which can be stable for a long period and can be used without any maintenance. CONSTITUTION:When an ID card 24 is inserted, a communication terminal 23 radiates signals from a transmitter 17 to the ID card 24 and with this radiated output, power is generated at the ID card 24. By supplying this power, the ID card 24 radiates personal information stored in the ID card 24 from the transmitter of the ID card to the communication terminal. Further, this output is received, demodulated by a receiver 18 and read in a control part 7. Therefore, since the power source of the ID card 24 is unnecessitated and signals are exchanged between the communication terminal 23 and the ID card 24 in a non-contact state, the maintenance of the ID card 24 is unnecessitated.
