A method of transmitting information to a portable computing device comprises, using a first communication protocol, transmitting a client to the portable computing device. The client configures the portable computing device to communicate with a distributor using a data transfer communication protocol. Using the data transfer communication protocol, the information is transmitted from the distributor to the portable computing device. Transmitting the information includes generating, at the distributor, a polling signal, detecting, at the distributor, an acknowledgement signal generated, in response to the polling signal, by the portable computing device, and generating, in response to the acknowledgement signal, a broadcast signal incorporating the information.
