Hmm, most other countries have free transfers between bank accounts. It's just the US (maybe a few others) still stuck in the stone age.
These debit cards very low fees, sometimes they work as both debit and visa card, so you can use them abroad too.
In the US, you only get a piece of the action if you use a credit card. Otherwise you still pay the higher, transaction-fee-included price, but you don't get any part of the transaction fee.
Or I guess the seller pockets the fee.
One-day ACH has been standardized and has begun to be rolled out.
In NZ for example, folks have their bank account # proudly displayed over a plate of cookies for purchase at 25 cents on a whim.
>free transfers between bank accounts
does it really matter if it was done through some third party service?
