Contactless data communication system, contactless identification tag and contactless identification tag control program
First Claim
1. A contactless identification tag for attaching to an object, the contactless identification tag comprising:
- a driving electric power generation part;
a first data reception part;
a first data transmission part;
a detachment detection part including a first detective resistor part and second detective resistor part that is electrically coupled to the first detective resistor part;
a control part including a voltage monitoring part that is electrically connected to a joint part through which the first detective resistor part is electrically coupled to the second detective resistor part; and
an adhesion part including a first adhesion part and a second adhesion part, the second adhesion part being separable from the first adhesion part, the first detective resistor part being formed on the second adhesion part, and a wiring of the first detective resistor part being contacted to a wiring included in the detachment detection part with a combining force strength that is weaker than a strength of an adhesive force with which the first adhesion part is attached to the object.

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.
