Abstract
An objective of the present invention is to provide a contactlessly readable tag, method for manufacture of contactlessly readable tag, identification device, and method for reading identifying information, capable of effecting an increased capacity in recorded information and improved precision in reading said recorded information. Provided is a contactlessly readable tag, comprising a metal part and an electromagnetic wave absorption body. The manner in which the metal part and the electromagnetic wave absorption body are installed is associated with identifying information. When the tag is irradiated with electromagnetic waves, it is possible to identify the identifying information on the basis of the amplitude of the electromagnetic waves reflected by the tag, and the shift in either the frequency or the phase of said reflected electromagnetic waves.
