If you don't want the Payment methods listed in the eShop package, you can always
set up your own payment method. Therefore you can have a merchant account with
another company (other than PayPal or Worldpay) and use that in your eShop.
1. Open eShop Administration. Click "Payment" under Settings.
2. Choose "Additional payment modules"
3. Click on "Add"
4. Enter the name for the payment method, web address of your merchant account,
other options and click "Next".
5. Enter the additional texts. Click "Next". You will be prompted for a few more
options. Click "Finish" to save the changes.
