Standard Model is the most well tested model yet, but still it is an incomplete theory. There are
fundamental physical phenomena in nature that the Standard Model does not adequately explain.
Complementary to the down-type quark studies in the $K$ and $B$ sectors, decays containing the charm
quark are a unique window to find the signal beyond the Standard Model. In this proceeding, 8
recent experimental results searching for the new physics signals through rare charm decays are
reviewed.
