Influence of electrically conductive walls on the range
NOTICE
Influence of conducting walls on the range
If there are metallic (reflecting) surfaces in the immediate vicinity of the transponder, this
can have a negative effect on the write/read range. Test the environmental conditions
before using the transponder.
