Blue Tooth and Infrared

Most modern mobile phones present an array of means for connecting. As well as using the cellular network, many phones have 3G and WiFi capabilities, and the ability to connect via Bluetooth or infrared. 

If a user sets their Bluetooth enabled mobile phone to “discoverable”, Bluetooth devices within range of the phone can request to connect to the phone and exchange messages and data. This can be used to send location specific marketing messages, such discount codes in a shopping mall. 

Outdoor display advertising can be fitted to send Bluetooth messages to people within range of the advertising. The messages can contain further information to offer a richer, longer lasting, experience. Note that these messages are often unexpected, so care must be taken not to be intrusive. There should be marketing collateral easily available and accessible that describes what the campaign is about.
