		hakfoo 6 months ago \| parent \| context \| favorite \| on: Offline card payments should be possible no later ... A lot of the time, that's still API smoke and mirrors. The API call is labelled "sale", but it performs an auth and at the end of the day the system still generates a capture or settlement-style message.

To an extent, yes. But functionally it doesn’t matter to the client of the gateway (or their downstream users, the cardholders).

If the gateway allows you to complete a sale request at 7am that doesn’t start an auth until 9pm, you have an offline payment by any other name.
