2.6. Validation field tests
Prior to monitoring the complete cold chain from South Africa,
real tests with fish were performed during a trip in a refrigerated truck from the Perishable Centre of Frankfurt Airport (Germany), to
the Perishable Centre of Vitoria Airport (Spain). For this first field
test, three prototype tags (two rigid and one flexible) were used.
The commercial data logger Smart TXi Label (PakSense, USA) was
also used for results comparison. This commercial label is not a
RFID tag.
