Well at least with phone tap there’s like a limit of $200, so maybe some company can corner a niche market where they only cover small daily purchases. No $10,000 credit balances or $2000 purchases and points and whatnot, just like $1000 balance limits and max $200 on purchases through tap.

You wouldn’t need quite as much capital that way, and I bet that would eat a good chunk of business from visa and MasterCard.
