Abstract
A method includes printing a first magnetic material onto a substrate. The first magnetic material has a first magnetic characteristic and encodes first information based on the first magnetic characteristic. The method further includes printing a second magnetic material onto the substrate. The second magnetic material encodes second information and has a second magnetic characteristic different from the first magnetic characteristic. The second information is encoded based on the second magnetic characteristic.
