Improvements of the SEMPOS payment model, which include making arbitration by the authentic third party, and use the Time Stamp server to keep from re-send attack, and analyze the advantage and disadvantage in detail.Finally, this model has been implemented by C language and put into practice, completed expected design objectives. Through this model's realization for the NFC in the industry, this provided a great direction for the expansion of applications.
