Square should admit that their real purpose is to track the customer without their direct permission and sell the data to the highest bidder.

Square is for morons who love Facebook profiling coz it's free.

I welcome to see the data that Square is tracking purchases, and if it is, how is this any different to XYZ Supermarket's loyalty program/card, and how are they doing this without breaking any laws.

(Oh, and they've handled $15bn in transactions, sans Starbucks, I doubt they need the moolah!)

What do you mean by show I am working? Projects? Love to, how?

As for comparing Square to loyalty cards, I have to give actual consent to the card issuer, with Square, they track me as a customer without permission or consent just because the merchant has done a deal with them.
