<P>PROBLEM TO BE SOLVED: To provide electromagnetic wave absorption cloth, to be used, for an example, in a physical distribution warehouse and the like for performing goods management using non-contact IC tags and a reader/writer compound peripheral device as a curtain to divide space, a cover for wrapping goods and the like, which is capable of properly classifying non-contact IC tags that need to be recognized for writing, reading and the like from non-contact IC tags that do not need to be recognized because they have been read already, and also capable of preventing circuit destruction of non-contact IC tags and tampering of data caused by electromagnetic wave radiation from the third party by accident or intentionally. <P>SOLUTION: The characteristics of this electromagnetic wave absorption cloth for non-contact radio wave recognition are that it has a conductive resin layer at least on one side of a base fabric and that transmission attenuation amount at 1 GHz is 3 to 20 dB. <P>COPYRIGHT: (C)2009,JPO&INPIT |
