PROBLEM TO BE SOLVED: To solve problems that the reading is incurred due to that a bar code is folded on contaminated in the case of using the bar code as an identifying means for identifying an article and there is no method for identifying many tags when a wireless tag is used. SOLUTION: This wireless identification tag is provided with an LC resonance circuit composed of a coil 8 and a capacitor 9, a resonance frequency setting circuit 12 as a collision preventing means for identifying individual signals without radio interference from plural signals when executing communication, a time slot setting circuit 13, encoded data setting circuit 14, memory circuit 17 for storing the identification data of the individual signals and a control circuit 18 for controlling respective circuits. Thus identification data can be identified by means of frequency, time zone and encoding. |
