This article describes two different methods to measure the electric dipole moment (EDM) of charged particles in storage rings. The frozen spin concept relies on a large fraction (possibly 100%) of the bending field to be electric while an rf Wien filter method can also be used in purely magnetic rings albeit at lower sensitivity. In recent years the JEDI collaboration has developed several important techniques that are applicable for both methods and major milestones are presented here.
