I don't understand why credit card networks (and banks in general) haven't stepped up their game with regards to micropayments (say, under $5). The marginal cost of any transaction is insignificant, and would be outweighed even by penny fees. Even if it required some extra steps for the vendor to become authorized to accept micropayments, and even with strict requirements around the number or total value of transactions a single card can be used with a single vendor during a time period, I think it could still work in everyone's favour.<p>One of the biggest fees on micropayments are the fixed transaction fees. Stripe is currently 27‰ + 5¢, which on a $1 transaction is nearly 8%! If those fixed fees could be made to go away for low-cost transactions, micropayments would work within the current system. Most people can accept 3% overhead, but most won't accept 8%.<p>It just seems like the entire problem is manufactured and not really an issue that can be solved until the banking systems just decided to solve it by changing their policies. I'm not even proposing a technical fix, it really seems to be a problem entirely with the current policies.<p>Edit: yes, I understand that Stripe is a gateway and processor, not an issuer or network, and that banks are often issures, but not the network. Yes, I understand that cards each have their own interchange rates, but many gateways like stripe have been just "averaging" them to provide low-volume retailers a fixed, predicable coat per transaction. I'm just saying that if the networks. E.g. Visa or MasterCard (or even discover or Amex despite being much smaller) could change their policies and requirements regarding fees for low volume transactions to remove fixed fees, and the vast majority of the issue with micropayments would be solved. I trust that the major payment gateways and browsers could work out a protocol to make use credit-card based micropayments very quickly and in a way that doesn't require additional third parties, beyond the payment gateway chosen by the person accepting the micropayment.
