Abstract: An anti-theft system for construction machines, comprising a memory which stores, as machine-side identification information, first identification information allocated construction machine by construction machine and second identification information allocated in common to plural construction machines, a first collating medium having the same identification information as the first identification information, a second collating medium having the same identification information as the second identification information, a collator which collates the identification information of the first or the second collating medium with the machine-side identification information, and an operation controller which cancels the inhibit of operation of the construction machine concerned when there is obtained a coincident collation result by the collator. With this anti-theft system, an owner of construction machines can manage the construction machines by only one type of a collating medium while preventing theft.

Abstract: An article identifying system for allowing a user, especially a visually handicapped person to identify an article correctly. The article identifying system 1 comprises a communication tag 100, each of which is attached to an article, and an information output device 200. Each of the communication tags 100 comprises: a memory 140 for storing an identifier assigned to the article with each of the communication tags 100; and an antenna 110 and a transceiver 120 for transmitting the stored identifier wirelessly. The information output device 200 comprises: a memory 230 for storing the information data associated with the identifier assigned to that article; an antenna plate 210 forming a planar surface on which one or more articles can be placed and a transceiver 220 for receiving the identifier from the communication tag 100 when the article with the communication tag is placed in a communication area on the planar surface; and a speaker 260 for outputting the information data from the memory 230.
