a memory storing configuration data configuring the reader device;
a first interface configured to connect the reader device to a host device;
a second interface configured to connect a physical token to the reader device; and
a controller configured to:
access the memory to read and write data;
communicate with the host device via the first interface;
communicate with the physical token via the second interface;
in response to a detection that no physical token is connected to the reader device, emulate a virtual token and transmit a first message to the host device indicating that the virtual token is connected to the reader device; and
in response to receiving at least one command from the host device addressing the virtual token, modify the configuration data stored in the memory in accordance with the at least one command.
