Barium ferrite (BaFe) is a ferromagnetic material used in magnetic stripe cards.

Barium ferrite is a natural crystal that does not absorb moisture, does not corrode, and does not undergo chemical change. Unlike magnetic particles (MP), BaFe does not have to be surface treated, does not have to be chemically stabilized, nor does it have to be maintained in a tightly controlled environment.

These properties of BaFe make it corrosion-resistant, moisture insensitive, and extremely stable in adverse environments. It is impervious to moisture degradation and typical playback wear.
