Also, there are four extra options defined in the file ShopFactory\Payment System\InternetSecure\definitions.txt. These are INTERNETSECURE_LANGUAGE, INTERNETSECURE_FLAGS, INTERNETSECURE_SHIPPING_FLAGS and INTERNETSECURE_TAX_FLAGS.
INTERNETSECURE_LANGUAGE is set to "english" by default, but this can be changed to "french" or "spanish"
INTERNETSECURE_FLAGS is the tax, recurring billing options and currency flag that will be used for all products. It is set to {US} by default, which means that the products are to be charged in US Dollars. Other options are:
INTERNETSECURE_SHIPPING_FLAGS and INTERNETSECURE_TAX_FLAGS take the same form as INTERNETSECURE_FLAGS, but are applied to the total shipping and tax values respectively.
