1. A non-contact IC tag system comprising:
- a plurality of non-contact IC tags, each of which includes identification information and a memory for storing a predetermined amount of data; and
a reader/writer that sends an operation command via radio to each of the non-contact IC tags, whereinthe non-contact IC tags include a plurality of slave IC tags and a master IC tag, andthe master IC tag holds memory configuration information that is used when building a memory space with a memory area of the memory of each of the slave IC tags and a memory area of the memory of the master IC tag wherein the reader/writer includesa memory control unit that stores identical data redundantly in at least two of the non-contact IC tags; and
a readout control unit that, when data cannot be read out from a predetermined non-contact IC tag in which the data is stored by the memory control unit, controls to read out the data from other non-contact IC tag in which the data is stored redundantly.

Abstract
A non-contact IC tag system includes a plurality of non-contact IC tags, each of which includes identification information and a memory for storing a predetermined amount of data; and a reader/writer that sends an operation command via radio to each of the non-contact IC tags. The non-contact IC tags include a plurality of slave IC tags and a master IC tag. The master IC tag holds memory configuration information that is used when building a memory space with a memory area of the memory of each of the slave IC tags and a memory area of the memory of the master IC tag.

7. A non-contact IC tag system comprising:
-
a plurality of non-contact IC tags, each of which includes identification information and a memory for storing a predetermined amount of data; and a reader/writer that sends an operation command via radio to each of the non-contact IC tags, wherein the non-contact IC tags include a plurality of slave IC tags and a master IC tag, the master IC tag holds memory configuration information of a slave IC tag linked to a memory area of the master IC tag, and each of the slave IC tags holds memory configuration information of a slave IC tag linked to a memory area of the corresponding slave IC tag wherein the reader/writer includes a memory control unit that stores identical data redundantly in at least two of the non-contact IC tags; and a readout control unit that, when data cannot be read out from a predetermined non-contact IC tag in which the data is stored by the memory control unit, controls to read out the data from other non-contact IC tag in which the data is stored redundantly. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-contact IC tag system comprising:
-
a plurality of non-contact IC tags, each of which includes identification information and a memory for storing a predetermined amount of data; a reader/writer that sends an operation command via radio to each of the non-contact IC tags; and a host apparatus connected to the reader/writer, wherein either of the reader/writer and the host apparatus includes a memory-configuration-information storing unit that stores memory configuration information for integrating memory areas of the memories of the non-contact IC tags to build a memory space; and a memory managing unit that manages the non-contact IC tags as one non-contact IC tag based on the memory configuration information stored in the memory-configuration-information storing unit. - View Dependent Claims (14)
