Ferroxtag is a new family of RFID tags suitable for
operation attached to metallic items. Operation frequency is 13.56 MHz.
Ferroxtag is a family of high frequency transponders based on a
ferrite antenna. Thanks to this high performance antenna, the tag
needs much less area than standard inlays for similar reading range.
The key feature is that enables real identification of metallic and
RFID hostile items by driving the magnetic field parallel to the
item the tag is attached to.
Ferroxtag key feature is the direction of the field activating the
device: it is not perpendicular to the identified item but parallel to
it; this means that the performance is almost independent of the
material of the item identified.
The Ferroxtag core is an outstanding high magnetic permeability ferrite
material that enhances the performance of the winding, thus reducing the
dimensions of the coil.
