Hi there We have Elavon's Hosted Payment Page integrated into the shopping cart and I just had a look at their Converge Payments which seem to be online transactions plus a POS terminal so I imagine that the online part of this still uses their Hosted Payment Page integration.
Sorry your post got missed but the integration is such that it will accept any currency and as long as the system you mention uses the same integration then there shouldn't be a problem. But could you maybe just call their support to make sure this is the same product?
