I propose to conduct comprehensive research and development for the implementation of the RFID-enabled vending machine in hotel rooms. With my expertise in market research, investment research, operations research, and product research, I will gather valuable insights to optimize the mini bar system. My proposal includes analyzing market trends, assessing the feasibility of the project, conducting cost-benefit analyses, and developing a prototype. My strong background in research and development, coupled with my commitment to delivering innovative solutions, makes me the best candidate for this freelancing project.
