Barium Ferrite

Our Barium Ferrite cards are most popular access cards and with good reason. With their barium ferrite inserts encoded by magnetizing spot in a specific pattern with specific polarities, they feature a factory-encoded site code and a unique card number to make it easy to regulate and monitor access to any area. They're the size of a standard credit card, allowing them to fit comfortably into a wallet, purse or pocket.
