A transponder is disclosed. The transponder includes a resonant circuit serving as an antenna, a load modulation module coupled to the resonant circuit, a current source coupled to the resonant circuit and a command interpreter configured to interpret a received initialization command. The command interpreter is configured to monitor input communication for a stop command signal and a charge & talk bit and if the charge & talk bit is not received within a predetermined time interval after receiving the stop command signal, the load modulation module is activated to provide a signal for transmission by modifying an incoming carrier wave through the load modulation module. If the charge & talk bit is received within the predetermined time after receiving the stop command signal, the current source is activated to provide a signal for transmission by generating pulses of current.
