One or more techniques and/or systems are disclosed for a biometric imager that can be integrated into a touch enabled computing device, and may be used to interact with the device. Upon touching the touch-enabled surface of the device, an image of at least a portion of the touch object can be captured and used in conjunction with identification of the user and/or for input to the device. The systems or techniques, described herein, may be integrated into a portion of the surface of such a device, and may comprise a luminescent layer that can emit photons upon touch, and an image capture component that can generate data indicative of an image of at least a portion of the touch object.
