1. A data exchanging system, comprising:
- a first IC chip;
a second IC chip different from the first IC chip; and
a reader for exchanging data with the first IC chip and the second IC chip, respectively;
wherein the first IC chip has a first receiving means for receiving an electric wave from the reader, power generating means for performing self-energizing power generation using the electric wave received, first memory means for storing data, and first radio output means for receiving a power source voltage from the power generating means to output the data stored in the first memory means to the reader by radio, the second IC chip has second receiving means for receiving data from the reader, and second memory means for storing a data group, and the reader has identifying means for identifying whether an IC chip with which data is exchanged is the first IC chip or the second IC chip, reader-side receiving means for receiving data sent by radio from the first IC chip when an IC chip with which data is exchanged is the first IC chip, reader-side memory means for storing the data, and reader-side radio output means for outputting the data stored in the reader-side memory means to the second IC chip by radio when an IC chip relative with data is exchanged is the second IC chip.

Abstract
A system for collecting data using a non-contact IC chip to manage the data using a computer. An IC chip sends data in a non-contact manner to a reader. The reader receives and stores the data in a memory. When an IC chip of a kind different from the IC chip is present near the reader, the reader sends the data stored in the memory to that IC chip by radio. The data received by the IC chip is supplied to a computer. The reader remains in a stand-alone setting and exchanges data with an IC chip.

6. A, data exchanging device for exchanging data with an IC chip, comprising:
-
identifying means for receiving identification data from the IC chip to identify a kind of IC chip;
receiving means for receiving, when the identifying means identifies the IC chip as the first IC chip, data sent by radio from the first IC chip;
memory means for storing the data received; and
transmission means for sending by radio, when the identifying means identifies that the IC chip as a second IC chip which is different from the first IC chip, the data stored in the memory means to the second IC chip. - View Dependent Claims (7, 8, 9)

10. A method for exchanging data between a first instrument into which a first IC chip is built, a second instrument into which a second IC chip different from the first IC chip is built, and a reader, the method comprising the steps of:
-
(a) sending an electric wave from the reader;
(b) sending by radio from the first instrument, when the first instrument receives the electric wave, information for identifying the first IC chip or the first instrument to the reader;
(c) sending from the reader, a data transmission request command in accordance with the information sent from the first instrument;
(d) sending by radio from the first instrument, data stored in an internal memory in response to the data transmission request command;
(e) receiving by the reader, the data sent from the first instrument to store in the internal memory;
(f) sending by radio from the second instrument, when the second instrument receives the electric wave, information for identifying the second IC chip or the second instrument to the reader;
(g) sending by radio from the reader, the data stored in the internal memory, in response to the information sent from the second instrument; and
(h) receiving by the second instrument, the data sent from the reader, storing the received data in an internal memory, and also sending the data to a computer.
