摘要： An EAS marker has a paintable or printable bias magnet material (56), which is either directly painted onto the EAS marker (55,65) or first placed onto a substrate material (58), which is then placed into the EAS marker. The material includes a magnetic powder mixed with resin and solvent. This 'bias paint' is then applied onto the EAS marker. The magnetic powder, resin, and solvent provide a very dense layer after drying, which has a magnetic material density that is usually lower than a rolled product, but is higher than that of the injection-molded magnet material. Printing the bias magnet allows nondeactivatable magnetomechanical EAS markers to be made using web-based mass production methods.

摘要： A method according to one embodiment may include detecting an activated electronic article surveillance (EAS) tag in an interrogation zone, and reading at least one radio frequency identification (RFID) tag in response to the detecting of the activated EAS tag in the interrogation zone to investigate a cause of the EAS tag in said interrogation zone. A method according to another embodiment may include detecting a condition representative of an activated RFID tag in a controlled area, and taking corrective action to prevent removal of the activated RFID tag from the controlled area.
