Unveiling Vulnerabilities in Serial Printer Point - of - Sale Systems: A Hardware Analysis Approach

Santosh Kumar Kande

Abstract: With the escalating rates of credit card fraud, securing payment systems, particularly physical point - of - sale (PoS) terminals, is imperative. This paper presents a comprehensive hardware - focused investigation into the security vulnerabilities of serial printer PoS systems, a crucial but often overlooked aspect of payment security. Utilizing a quantitative survey research approach, the study delves into these systems hardware and software configurations, addressing key research questions concerning their baseline hardware, software capabilities, and susceptibility to modification. The study identifies potential entry points for exploitation through meticulous disassembly and component analysis and examines the feasibility of firmware modification. Furthermore, the research sheds light on the critical role of device manufacturers in understanding and fortifying the security features of peripheral devices. The findings underscore the need for heightened vigilance and proactive measures to safeguard PoS systems against emerging threats in the digital landscape.
