Abstract: An electronic device and corresponding method are used for acquiring, storing, and transmitting radio frequency identification (RFID) credential data previously stored in another device. The electronic device includes a mechanical housing, electronic circuitry mounted within the mechanical housing, a power source coupled to the electronic circuitry to provide electrical power to the electronic circuitry, and an interface mechanism coupled to the electronic circuitry in a manner to allow a human user to effect operation of the electronic circuitry. The electronic circuitry is configured to (a) receive an initial response RF signal emitted by the other device in response to an initial interrogation RF signal, where the initial response RF signal carries the RFID credential data, (b) acquire the RFID credential data from the initial response RF signal, (c) store the RFID credential data, and (d) transmit to an interrogator device an outgoing RF signal that carries the RFID credential data.
