Ask HN: Isn't it sad that till this day we pay credit card fees per transaction?

I wish there was an online only bank where you could deposit money, and use their oauth2 like process to pay online anywhere. at no cost to seller or buyer.

The company would make money by cash on hand and investing some of it, (most people would have lot of cash left over in their accounts for long periods of time), and to make it even simpler the bank didn't have to pay .002 cent in interest every month.

Paypal could have been the it, but they charge just like credit cards, and suck more than a bank would.
