Everyone here seems to be complaining about the anonymous tracking, which isn't really an issue for "normals". Its a relatively useless complaint too as that data already exists in the credit card network.
The real issue with this is that most SMBs are unsophisticated when it comes to the technology stack they use. I saw this firsthand in many ways working at Swipely (swipely.com) as we figured out product market fit. While things like 'see where else your customers shop' might seem like an interesting feature from an outsiders perspective, the businesses don't actually care. They often barely have the bandwidth to worry about their own customers.
