Charm in electron proton collisions is a particularly large and interesting field. For this summary two topics particularly relevant for HERA have been selected. First the study of inelastic J/psi production in both the photoproduction and the electroproduction regime, study still needed to clarify the J\psi production mechanisms. Second the analysis of D* photoproduction events, study than can lead to a better understanding of the photon structure.
