They are following your habbits and branding touchpoints already, you are being targeted based on a profile even as you browse here. So cash or no its happening. Might as well have an accurate profile
Handling cash is expensive and inefficient.
People are always screaming about increasing productivity, then some people dont like they way they do it.
We are all a type of nimby with some change.
Cash will always have a place for a long time to come, but I dont see the fuss about major department stores not taking it.
If Woolies stops taking it, that would be a problem.
