Coordinating Multiple Contactless Data Carriers

摘要

A contactless transponder device is provided with multiple ICs. A first IC includes a first contactless transponder interface circuit configured and arranged to respond to a contactless field by providing a first identifier of the first IC. A second IC includes a second contactless transponder interface circuit configured and arranged to respond to the contactless field by providing a second identifier of the second IC. A controller is configured and arranged to inhibit the first IC from responding to the contactless field.
