"The system means centres can analyse data such as how long visitors stay, where their favourite spots are and their preferred routes as they move around a mall. Shopping centres argue the system benefits both customers and retailers and insist privacy is not compromised because individuals are not identified," writes Steven Morris.
"Under the FootPath scheme a series of monitoring devices are installed throughout a shopping centre. The units pick up signals from a customer's mobile phone and can pinpoint the person's position to within 2m. The data gleaned is fed to a processing centre where it is collected, analysed and fed back."
An earlier CNN article looks at experiments in the US at malls managed by Forest City Commercial Management.
