We show that at low energy, any multidimensional universe containing two branes can be described as a two-sheeted spacetime in the formalism of the noncommutative geometry. This equivalence implies a model-independent phenomenology. Matter swapping between two branes is predicted through fermionic oscillations at very low energy. This phenomenon can be experimentally studied with present-day technology and could allow to test the braneworld hypothesis. An experimental setup is suggested, which relies on the Hänsch frequency-comb technique and the use of a polarized ultracold neutron gas. Some tracks are also suggested to study the phenomenological consequences at the typical energy scale involved in modern colliders.
