Consumers with Bluetooth-enabled phones will receive a message when they enter one of the hotspots asking whether they would like content from Coke. If they agree to the service, their phone will download videos and other material.
The two companies have worked together for two years and collaborated in a campaign around the Olympic Torch Relay.
Steve Chao, co-founder and CEO of Pioco, claims conversion rates of 35% for Bluetooth campaigns, with the rate rising to 65% when participants are prompted to turn on the Bluetooth function on their phones.
