A communications system includes first and second beacon devices capable of wireless
message transmission and at least one portable device capable of receiving such
message transmissions. The first beacon is arrange to broadcast a series of inquiry
messages according to a first communications protocol, such as Bluetooth. The portable
device detects such inquiry messages and replies with an identifier for the portable
device. The first beacon then transmits the received identifier to the second beacon,
with the second beacon and portable device configured to perform a service interaction
when triggered by the second beacon receiving the portable device identifier.
