Seal set of security keys of the air compressor, air compressor, air compressor management method

摘要

PROBLEM TO BE SOLVED: To provide novel security means that facilitates management of a security key.SOLUTION: A security key is used to lock/unlock a compressor, and comprises a seal tag which can be stuck to any belonging of a user of the compressor. The seal tag includes an IC chip in which unique identification information readable by the compressor is recorded. The security key configured by the seal tag can be freely stuck to any belonging of the user, thereby allowing individual users to attach the security key to articles (a mobile phone, a driving license, etc.) that may be carried with high probability. The security key allows a user to add a function of a key to a desired article (that the user intends to carry with high probability) in an ex-post manner, thus eliminating a concept of "possessing an independent article as a key" which has been taken for granted.
