mastercard sends your transaction data live to banks. They sell your data to third parties for marketing, profiling and the likes. Credit score is the least of your problems.
I know because I developed a system, in a major European bank, enriching their transaction data with mastercard data for live, predatory marketing.
Me in yurop, using a debit MasterCard, never needed a credit score. Who has my data, what are they doing with it, and how do I burn down their server?
(The answer, kids, is Stripe. Give it some years, it will be lit)
