當門巿收銀機銷售端點(Point of Sale)轉型成服務端點(Point of Service)。POS系統在不同應用環境，不僅改變外型更提升資訊服務。經濟發展生活型態改變，POS具備的各項優點，使全球各大零售業、餐飲業、觀光百貨業、便利商店及其他服務業者對POS系統極具依賴。
雲端POS尚處萌芽的階段，國內企業應用方面仍未見有較成熟的案例。學術界在雲端POS的管理實施議題上研究報告十分有限。因此，本研究以流通零售業為背景，探討雲端POS導入的相關議題。
本研究以雲端使用者及雲端供應者為對象，透過案例探討雲端運算的經濟及效能優勢，並針對廣泛需求進行分析及實證性歸納。研究發現，為達到POS雲端化，雲端運算環境須具備標準化的技術與系統功能，才能確保互通、易於整合與轉移。雲端運算亦必須在開放式環境中演變，以確保供應商開發之系統能符合消費者需求。本研究結果可作為企業欲導入雲端POS時，針對技術、架構、成本、效益、風險可行性評估之參考。

When Point of Sale revolutionizes to Point of Service, the appearance of POS system changes, along with expanding information service provided, under different application environment. The advantages brought by POS results in retail, catering, tourist, convenience store and other service industries worldwide to become highly dependent on the POS system.
The application of POS in enterprises of Taiwan is still under development and research on the management and application of Cloud POS is very scarce. Therefore, the main focus of this research is to discuss the implementation of Cloud POS in retail industry.
In this study, an empirical case study is conducted to discuss the economic and performance advantages of cloud computing, targeted at cloud users and cloud providers. Results of investigation reveals that cloud computing environment has to be equipped with standardized technology and system function in order to reach interoperability, ease in integration and ease in transfer. In addition, cloud computing must evolve as an open environment, to ensure the system developed by the supplier meets the requirements of customers. Hopefully, results of this research can be utilized as a reference for enterprises to evaluate technology, architecture, cost, benefits and risk analysis in feasibility study upon the implementation of Cloud POS.
