10.2 Specific risk factors
10.2.2 Changes to mobile device identification
SkyFii collects and uses the unique device MAC address for analysis of the presence of devices which are not connected to the wireless network. Changes to the way mobile devices search for wireless networks, including masking or randomisation of the MAC address, could render any of SkyFii’s products and services which rely on presence analytics data (or the ways in which such products and services are currently implemented) less attractive or redundant, which could have a material adverse effect on its business, operations and financial performance, and the price of the Shares.
