Gateway Vendor is one of the defined Vendor Types and describes how the Vendor equipment looks
The Gateway Vendor must set up his own Gateway to communicate to the Eskom Server via a permanent communication line. The Gateway Vendor will have only one Vendor Account and all Vend requests will be handled via this Gateway and account. Behind the Gateway, the Vendor may have many proprietary Vending Terminals of different capabilities but all of that is transparent to Eskom since the Terminals never communicate directly with the Eskom Server. This configuration is typically the way that EasyPay and the Banks would operate but note that it is also possible for a Regional Vendor or even an Area Vendor to be configured on the Server as a Gateway Vendor.
