Abstract
An example device includes a first inductive antenna to activate a radio frequency identification (RFID) device and to receive an identification signal from the activated RFID device, a second inductive antenna to emulate the RFID device by transmitting the identification signal of the RFID device, a switch positioned between the first inductive antenna and the second inductive antenna, and a controller to selectively open the switch to decouple the first inductive antenna and the second inductive antenna or close the switch to couple the first inductive antenna and the second inductive antenna.
Claims15
A device, comprising:
- a first inductive antenna to activate a radio frequency identification (RFID) device and to receive an identification signal from the activated RFID device;
- a second inductive antenna to emulate the RFID device by transmitting the identification signal of the RFID device;
- a switch positioned between the first inductive antenna and the second inductive antenna;
- and
- a controller to selectively open the switch to decouple the first inductive antenna and the second inductive antenna or close the switch to couple the first inductive antenna and the second inductive antenna.
An apparatus, comprising:
- a tag coupling portion including an array of at least two inductive antennas;
- a reader coupling portion including an inductive antenna;
- a switch portion to selectively couple or decouple the inductive antenna of the reader coupling portion to each of the at least two inductive antennas of the tag coupling portion;
- and
- a controller to operate the switch portion to selectively couple the inductive antenna of the reader coupling portion to one antenna of the at least two inductive antennas of the tag coupling portion while decoupling the inductive antenna of the reader coupling portion from all other antennas of the at least two inductive antennas of the tag coupling portion.
A method, comprising:
- causing a switch to be closed, the switch being to selectively couple a reader portion inductive antenna to a tag portion inductive antenna;
- receiving an identification signal by the tag portion inductive antenna;
- and
- transmitting the identification signal by the reader portion inductive antenna.
