What exactly are retailers doing with this data, that they couldn't do before?

They've been doing this since loyalty cards became popular in the 90s.
It seems somewhat benign, and not very useful, that they know I spent 45 seconds in front of the yogurt section, compared to the average at that time of 28 seconds.

The part about eending ads to your device is FUD, any app that starts doing that without my permission is getting uninstalled straight away.
