We present a method used to determine a minimal and complete set of second order invariants of surfaces in codimension two. It has been applied to determine these invariants in different settings. That is, when the surface is immersed in Euclidean space or in Minkowski space. We present the case when the surface is inmmersed in R^{2,2}. An application of these invariants provides a nice intrinsic expression of the asymptotic lines on the surface. This is a joint work with Pierre Bayard and Victor Patty.
