  Recent disagreement between experimental measurments of CP violating
asymmetry in D -> K+ K- and D ->pi+ pi- and theoretical Standard model
expectation motivated many studies within the Standard model and beyond. Rare
charm decays offer new probe of possible signals beyond Standard model. CP
conserving and CP violating contributions within the Standard model and beyond
are reviewed for inclusive c -> u gamma and c ->u l+ l- and exclusive D ->V
gamma, D ->P+ P-, D+ -> pi+ l+ l-, D -> l+ l- decays.
