Readability of ultra-high frequency (UHF) passive tag applied on food depends on many factors, such as tag features (inlay design, chip type), reader antenna polarization, tag-to-reader antenna distance and orientation, reader transmitter power output, environmental characteristics, packaging material, as well as product composition. In a real production context, apart the environmental interference which can affect RF wave propagation, both product and packaging characteristics (shape, material, composition) must be considered. The goal of this work is to identify technological features and limits of UHF RFID systems for the electronic identification of food products in different kind of packaging. The effects of different factors as food product, packaging material and tag type were considered for UHF transponder readability evaluation. At this purpose, different tag models and food product categories were subjected to performance analysis comparing, in different item positioning, the tag readability. Food products in their original packaging were considered individually and in stacked/flanked or adjoined configurations in order to simulate item level tracking in production and selling contexts.

Abstract
Readability of ultra-high frequency (UHF) passive tag applied on food depends on many factors, such as tag features (inlay design, chip type), reader antenna polarization, tag-to-reader antenna distance and orientation, reader transmitter power output, environmental characteristics, packaging material, as well as product composition. In a real production context, apart the environmental interference which can affect RF wave propagation, both product and packaging characteristics (shape, material, composition) must be considered. The goal of this work is to identify technological features and limits of UHF RFID systems for the electronic identification of food products in different kind of packaging. The effects of different factors as food product, packaging material and tag type were considered for UHF transponder readability evaluation. At this purpose, different tag models and food product categories were subjected to performance analysis comparing, in different item positioning, the tag readability. Food products in their original packaging were considered individually and in stacked/flanked or adjoined configurations in order to simulate item level tracking in production and selling contexts.
