Where we've seen a ton of transactions right now is with people paying monthly rent.
I don't understand this. Perhaps it's an American thing, but here in EU, I just put my landlord's account numbers into my online banking and I can transfer them money for essentially free. I even set up a standing order so it'll pay the same amount at a fixed day per month. I don't have to worry about paying rent. How does a landlord accept money via their credit card?
