[M]ost of the two billion Mastercard holders aren’t aware…

Google paid Mastercard millions of dollars for the data…

So it was effectively free?

I’ll patiently await my refund.

I saw Google’s list of things they think they know about me. They got fleeced by MC.

Collecting and selling data on what you spend money on is a big bit of MC’s business. It would be more surprising if this didn’t happen.

I wonder if this is legal. In Europe, purchase data might be “sensitive data” according to the GDPR, and that means both Google and Mastercard could face seriously crippling fees.

Of course, the US is different, but even so, it’s not obvious that selling such data about individuals is legal. IANAL, but this is quite brazen.

Dang. So everytime Google Rewards gave me $.10 credit for saying, “I don’t remember how I made a payment”… they knew all along…?

Great. Now in addition to all my purchases, Google also knows I am a liar…

It would be much better to create its own cryptocurrency. Just check how many cryptos and ICOs have already be done https://cryptodiffer.com/

Where’s my cut?

When I received my MasterCard this year, I read the agreement. The sale of anonymised information for marketing purposes is explicitly stated, and there is an 800 number to call to opt-out. Sure, I’d prefer if it was opt-in instead, but they’ve been doing this forever.
