We use a relativistic highly improved staggered quark action to discretize charm quarks on the lattice. We calculate the masses and the dispersion relation for heavy-heavy and heavy-light meson states, and show that the discretization errors are at the few percent level. We present our preliminary results on a precise calculation of $f_{D_s}$ and $f_D$, and we discuss the future prospects of this method.
