  We propose that the intrinsic geometry of holographic screens should be
described by the Newton-Cartan geometry. As a test of this proposal, we show
that the evolution equations of the screen can be written in a covariant form
in terms of a stress tensor, an energy current, and a momentum one-form. We
derive the expressions for the stress tensor, energy density, and momentum
one-form using Brown-York action formalism.
