PROBLEM TO BE SOLVED: To read much more data at high speed in a card reading system where a card reader incorporating a guide coil reads data stored in the card incorporating the guide coil. SOLUTION: In a card reader 10, data is read from a card 20 constituted of a memory part 22 having a memory 221 storing data, and a coil part 21 having a power reception/supply coil L21 and a signal transmission coil L22. In the card reader 10, a power supply coil part 11 that is connected to a signal supply circuit 12 for power, which generates a prescribed oscillation signal, and has a power supply coil L11 and a signal reception coil part 13 which is connected to a signal reception circuit 14 analyzing the received signal and has the signal reception coil L12 are made to be different bodies and they sandwich the coil part 21. |
