After reading such news I have an obvious question. Does anyone know a PayPal-like service, that allows to hide the destination of my transactions from Mastercard / bank, but with a good privacy policy? Or how else can I restrict the usage of my financial data by mastercard or bank?
Besides the other user’s recommendation, have a look at coincards. Haven’t used them yet, but they have gift cards for a lot of things, online and physical brands too.
