Gas and liquid containers.
Gas cylinders and beer kegs have always been a very difficult
task for RFID tags. UHF tags are almost impossible to be used: both
reader and tag get detuned, and reflections make difficult get
accurate readings. In most of the cases high frequency tags
are used with a large spacer to the metallic surface. This is a
solution, but the reading range is very limited, and the tags have
to be placed in a very visible place, to ensure enough magnetic
field to power the IC.
Ferroxtag enables mounting on the handles, in a very well
protected place, and still keep a safe reading range: 10 to 20 cm
with a simple 1 watt reader.

This picture shows an example where the tag is even ribbeted on the
handle, preventing vandalism. The Ferroxtag can be placed in such a
place thanks to the ability to attract the magnetic field.
