Abstract

Visual and audio communication interface for a perishable integrity indicator system which includes a RFID transponder and perishable integrity sensor. A perishable integrity indicator system includes a RFID transponder and a perishable integrity sensor. The RFID transponder includes a RF integrated circuit coupled with an antenna. The sensor monitors the time and temperature of the perishable. A freshness determining module receives time- and temperature-dependent measurement data from the perishable integrity sensor and determines a current freshness status. A communications interface to the RFID transponder permits a RFID reader to retrieve current freshness status data corresponding to the freshness status determined by the freshness determining module. The system further includes a power management module. The visual and audio communication interface provides a communications means for sending sensor alerts, sensor setup and history as either a supplement to the RF communication or as an alternative to RF when RF is either not available or not able to communicate.
