Contactless data communication system, countactless identification tag and contactless identification tag control program
First Claim
1. A contactless data communication system, comprising:
- a reader-writer device; and
a contactless identification tag,the reader-writer device including;
a data communication means that is capable of data communications with the contactless identification tag; and
an electromagnetic wave transmission means for supplying power that transmits an electromagnetic wave for supplying power to the contactless identification tag at the time of data communications by the data communication means; and
the contactless identification tag including;
a driving electric power generation means that generates driving electric power from the electromagnetic wave for supplying power transmitted from the reader-writer device;
an attachment means that attaches the contactless identification tag to a given object;
a detachment detection means that detects whether the contactless identification tag attached to the given object by the attachment means is detached from the given object; and
a specific information display means which displays specific information based on a detection result obtained by the detachment detection means.

Abstract
A contactless data communication system includes a reader-writer device, a contactless identification tag including a plurality of contactless identification tags, and baggage including multiple pieces of baggage. The reader-writer device includes a data reception part, a data transmission part, a control part, an operation part, and a display part. The contactless identification tag includes a data communication part, a data control part, a voltage monitoring part, a detachment detection part, a display processing part, and an electrophoresis display device. The voltage monitoring part and the detachment detection part detect a voltage change caused when the contactless identification tag is detached from the baggage, so as to detect that the contactless identification tag is detached.
