I took an existing thing and put it inside another existing thing. That’s a novel idea, right?

We could put card terminals in everything! Put card terminals in the fridge to pay for food?

I can’t think how this is any better than just using the card you already saved on the account. Even from their point of view, this is an extra step in the payment process.

That’s why all these microtransactions are in their own made-up currency.
