Abstract

A worker carries a sensor that senses a tag device, preferably a passive RFID tag, in or on an article being processed. The sensor obtains wirelessly from the tag device identifying data, such as a numerical tag, which has been recorded as corresponding to a specific article. A computer connected with the receiver uses the identifying data to obtain a network address on a computer data network. Data relating to the worker contact with the article is sent over the network to the address accessed, and the server, or a management computer attached to it, causes a record to be stored reporting the access regarding the article, and other bookkeeping or process control activities are performed as claimed.
