Methodology of a dynamic test bench to test ultra-high-frequency transponder ear tags in motion

The experiments showed that neither the transponder holder material (polyvinyl chloride vs. extruded polystyrene) nor the reader settings examined (triggered read vs. presence sensing) had a significant influence on the average of readings of the different transponder types. The parameter 'number of rounds' (10 vs. 15 vs. 20) did not show a significant effect either. However, significant differences between speed (1.5 m s−1, 3.0 m s−1), transponder orientation and the fourteen transponder types were found. The two most suitable transponder ear tags for cattle and pigs have been determined by comparison.
