Recent experimental bounds on rare charm decays offer a chance to improve our theoretical understanding of physics present in c→uγ and c→ul+l− transitions. Standard Model and New Physics contributions are reviewed for inclusive and exclusive D→Vγ

decays. Observables important for search of New Physics are discussed. Possibility to observe CP violation in rare charm decays is questioned.
