[liberationtech] Recently sold sensenetworks has creepy buying habits tracking feature

Hi all,

A few months back a ad platform sensenetworks was recently bought by a 
large US corp. Among their offerings, is the not uncommon real-time 
bidding auction for ads:

However, what shocks me is the claim that they're able to track users 
buying items in physical stores. How they do this, is completely beyond 
me. (https://www.sensenetworks.com/retail-retargeting/)
