A filling station has a telephone line that serves all their credit card readers, including those on the pumps. This is an extra expense, particularly if you're looking at a standalone, unattended charging station. I won't discuss the security implications of transmitting credit card data wirelessly, etc. here... The QR code or phone number approach is very smart and avoids the whole business of dealing with credit card data in transit. All that is kept on the back end, and all you are doing is managing login and duration data.
