Problems solved by technology
If the storage area is managed according to the specified data storage unit, when the data less than the size of the unit is stored, an unused storage area will be generated, which will further reduce the storage utilization rate.
[0009] Furthermore, in the above-mentioned IC card, there is also a problem that since the processing for R / W is the same, it is difficult to perform processing according to a plurality of R / W

Embodiment Construction
[0115] FIG. 1 shows an example of a contactless card system using R / W1 and IC card 2 . R / W1 and IC card 2 use electromagnetic waves to transmit and receive data in a non-contact manner.
[0116] Once the R / W1 transmits a predetermined command to the IC card 2, the IC card 2 receives the command and performs processing corresponding to the command.
[0117] As the IC card 2 of an embodiment of the information processing device of the present invention, once R / W1 sends data to the IC card 2, it receives the instruction, processes the received instruction, and sends the response data corresponding to the processing result to the IC card 2. R / W1.
[0118] R / W1 is connected to the controller 3 through a specified interface (such as RS-485A), and the controller 3 provides a specified control signal, and processes according to the control signal.
[0119] Figure 2 shows the structure of R / W1.
[0120] In the IC21, there are connected via the bus: a DPU (Data Processing Unit: Data ...

The present invention relates to a method and apparatus for processing a command received from a provider apparatus (1) by utilizing a memory section (66). The memory section (66) comprises a first area including a plurality of area definition blocks each of which stores information relating to a predetermined area (BN 0 ..BN 1 ) in a second area of the memory section (66) which is used by one or more provider apparatuses (1), wherein the second area includes a plurality of user blocks managed in a block unit having a predetermined size, each of the plurality of area definition blocks has the predetermined size and the block unit being used by a plurality of provider apparatuses (1). The first area size is based on the number of provider apparatuses and the second area size is based on subtracting the first area size from the size of the memory section (66).
Description
[0001] This application is a divisional application of an invention patent application with an application date of June 24, 1997, an application number of 200410064265.4, and an invention title of "Information Processing Method and Information Processing Device". technical field [0002] The present invention relates to an information processing method and an information processing device, in particular to an information processing method and an information processing device for receiving an instruction from a specified user in an unstable state, processing the instruction, and sending the processing result. Background technique [0003] IC cards (smart cards) used in electronic money systems or security systems are being continuously developed. [0004] This type of IC card is equipped with a CPU that performs various processes and a memory that stores data required for processing, etc., and transmits and receives data when it is in contact with a specified read / write (R / W)....
