RFID temperature monitoring: trends, opportunities, and challenges

The arrival of radio frequency identification (RFID) technology as a logistical tool for the perishable food supply chain has presented the industry with a

learning curve that is both steep and long; for supply chain visibility, there is still no magic bullet. Nonetheless, RFID tools are increasingly being understood, and leveraged, in the context of specific applications driven by well-defined value propositions. This chapter examines an emerging RFID application that will extend the range of logistical options to include monitoring and interpretation of time-temperature history of perishable goods. Here we summarize some of the perspectives gained from experience in developing this new type of solution.*

The following enablers and drivers are believed to be setting the stage for a large-scale move toward RFID in transit temperature-monitoring processes:


1. Application-specific integrated circuit (ASIC) technology 2. RFID air interface standards


1. Avoidable spoilage losses associated with time-temperature exposure

2. RFID data capture/management infrastructure developments

Regarding the two enablers cited:

• ASIC technology can be seen as the simplification of electronic devices arising from highly economical, custom-designed silicon chips. Without ASIC chip designs, for example, pallet-level monitoring of goods such as produce might not become economically feasible.
