A method and system for collecting information associated with warewashing activities is disclosed. Articles to be cleaned by a warewasher are placed in racks designed to fit inside a wash chamber of the warewasher. Each rack is assigned a unique identifier (ID). No two racks are associated with the same unique ID. An Radio Frequency IDentification (RFID) tag is embedded within or placed on the outer shell of each rack. The RFID tag of a rack is programmed with the unique ID assigned to the rack. An RFID reader reads the unique ID of each rack as the racks are placed into the warewasher. The RFID reader transmits the unique ID to a host computer where the unique ID is stamped with a time reference, stored and eventually uploaded to a server computer. The unique ID and associated time reference are analyzed by the server computer, the host computer or a client computer connected to the server computer in order to monitor performance of the warewasher. For example, the analysis may calculate the total number of racks provided to the wash chamber over a given period in time.
