> What processing companies are available to use that don't sell your transaction data by default?
Thankfully merchants are generally opaque in terms of the metadata provided to the payment processors. I for one am thankful my card statements have "Amazon purchase" instead of the specific item purchased, for instance.
I would be surprised if especially large merchants (like Amazon or Walmart) would submit to this as they I would imagine they have massive bargaining power when it comes to transaction fees and would gain little in sharing that data with the payment processor.
I could see companies whose lines of business tend to have higher fraud rates take advantage of providing more data in exchange for cheaper fees.
