Previously, I was told
The test merchant is going to Westpac test host which only supports
AUD
andNZD
So it is a limitation for the test mode only?
Usually a customer expects to be charged in the currency of the shop’s frontend, and he can be dissatisfied being charged in an unexpected AUD
currency.
He can be dissatisfied, for example, because of unpredictable conversion rates. Of course, a conversion fee is usually small, but a lot of customers are not rationally-minded and they would be dissatisfied.
Some customers plan they purchases (and even use a prepaid virtual card with a concrete limited amount for a concrete purchase), and they can drop a payment just because on an extra unexpected dollar.
