Abstract
A coded tag includes a substrate. The coded tag includes a first magnetic material associated with the substrate. The first magnetic material has a first magnetic characteristic and encodes first information. The coded tag includes a second magnetic material associated with the substrate. The second magnetic material encodes second information and has a second magnetic characteristic that is different from the first magnetic characteristic.
