Recently, both BaBar and Belle experiments found evidences of neutral D mixing. In this paper, we discuss the sensitivities of the measurements of D mixing parameters at BES-III. With CP tag technique at psi(3770) peak, the extraction of the strong phase difference in D-0 -> K pi decay at BES-III are discussed. We also make an estimate on the measurements of the mixing rate R-M by using the coherent data at psi(3770) peak. The CP violation in D system is predicted with an unobserved level in the Standard Model. Any significant CP violation in the D system indicates the existence of new physics. The sensitivity of the measurements of CP violation in the D system is estimated in the coherent D decays. Finally, the search for the rare D decays are discussed, in which some of the forbidden decays are smoking gun of new physics.
