The invention is directed to a wireless handheld device that securely accesses one or more remote devices subject to locally authenticating a user via biometrics. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode device. At least one transmissionreceive point includes a base station that supports wireless communication between a network and user equipment, such as, a mobile device.
