How should I stick the transponders on the bibs?

What is the difference between Transponders with foam spacer and Simple Transponders?
Bib transponders are made for running events or other events where the bib is worn close to the body. The foam spacer on the bib is there to provide some distance between the transponder and the human body, as the human body is made of about 70 % water, which absorbs the radio frequencies used in timing systems.
The simple tags are for applications away from the human body, i.e. on bike race numbers.
What is the size of the Transponder?
Transponder with foam: 108 x 27 mm
Simple Transponder without foam: 105 x 25 mm
