  The search for $D^0\bar{D}^0$ mixing may carry a large discovery potential
for new physics since the $D^0\bar{D}^0$ mixing rate is expected to be small in
the Standard Model. This paper gives a brief review of the experimental
techniques which can be used to search for $D^0\bar{D}^0$ mixing in the future.
Some ideas, applicable to future mixing searches at hadron machines (such as
Tevatron and LHC), and fixed target experiments (such as HEAR-B) are
introduced.
