A New Cash Register for Fuel Stations with Resistant Outdoor Conditions: Design Considerations

The Head of Revenue Administration (HRA) in Turkey imposes the obligation to use new generation payment recording devices (NG PRDs) at fuel stations. The pump and the cash register were separate units in old payment systems, and communication was provided via an interface. However, there are some security vulnerabilities in these systems due to the interface being separate from the cash register. In addition, it is known that due to the high fuel tax rates, significant losses occur due to tax evasion. Although the use of NG PRD has been made compulsory, no product in the market complies with the current legislation. Therefore, there is a need for these products to be developed for secure data communication in fuel pump cash registers, prevention of tax evasion, and monitoring of the informal economy in the fuel sector. This study aims to design and manufacture prototypes of NG PRDs and components for fuel stations in accordance with the technical guide of the HRA legislation. The main feature sought for NG PRDs is to ensure the continuity of communication between the pump and the cash register.
