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.
