As self-checkout technology advances in today's retail settings, ensuring smooth interaction between various devices has become an essential task. With the increasing complexity of systems that include barcode scanners, payment terminals, RFID readers, and mobile applications, innovative solutions are necessary to close communication gaps, boost efficiency, and enhance customer satisfaction. This research presents a multi-layered approach that incorporates standardized protocols, middleware, AI-powered coordination, and real-time monitoring to enable seamless device communication. Tests conducted in a simulated environment showed notable improvements, including a 58% reduction in communication delays, a 68% drop in error rates, and a 67% decrease in the time it takes to resolve issues, along with a 28% increase in transaction processing speed. The paper wraps up by discussing ongoing challenges and future directions for improving system scalability, privacy protection, and robustness.
