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.
