Article management system
First Claim
1. An article management system, comprising:
- a central response device being adapted to be worn by a user; and
a central management device, incorporated into an article, that can communicate with the central response device wirelessly,wherein the central management device comprises;
an interrogator that communicates wirelessly with the central response device;
a detector that detects a communication distance between the interrogator and the central response device; and
an alarm portion that notifies the user when the communication distance detected by the detector reaches or exceeds a standard value.

Abstract
The present invention is an article management system using a central management device with an interrogator and an alarm portion. Because the central management device and a central response device worn by a user of the system are provided separately, loss of the central management device can be prevented. The central response device is worn by a user. The central response device communicates with the central management device wirelessly and includes a detector that detects when the communication distance reaches or exceeds a given value and an alarm portion that notifies the user of this. The central management device communicates wirelessly with one or more articles in which a response device is installed.
