Your purchase data is for sale
I was reading an article posted to Hacker News recently, “Google and Mastercard Cut Ad Deal to Track Retail Sales”, about how Google is buying transaction data from MasterCard. I’ve noticed when setting up a new bank account or getting a new debit or credit card there is often a little notice inside about their privacy practices and how you can opt-out, but they don’t make it clear to what extent this is possible and what information it is that they sell and to whom.
Protecting Your Privacy
The best way to protect your financial privacy would be to use cash, but for many reasons that are not practical especially for modern convenience and things like online shopping. The point of these suggestions is just to limit the amount of personal information and marketing data being collected and shared. Keep in mind the retailers and merchants you do business with may retain and sell your data as well, this is exactly how most store rewards programs work.
I also used Abine Blur in the past, but I found the interface for virtual cards was lacking and the company hasn’t updated it in years.
