1. An electronic device, comprising:
- a housing having a surface and a recess that extends from the surface, the recess having walls that extend to a terminus surface, wherein the walls are observable only from a location that is outside of the housing at a viewing angle that is non-orthogonal to the surface; and
a mark laser etched on at least one wall and having physical characteristics corresponding to a laser beam impinging the at least one wall at the viewing angle, wherein when the mark is observed at the viewing angle, the mark has an appearance corresponding to the laser beam impinging the surface at an angle that is orthogonal to the surface.

Abstract
An electronic device includes a housing having an opening that includes an interior surface with a portion that is only viewable from an external vantage point at a viewing angle that is other than ninety degrees (90°). The electronic device also includes a SIM card tray that is removable from the housing via the opening and the SIM card tray includes an angled surface. Information is encoded in the form of text that is laser etched on the angled surface. The text is characterized as having an aspect ratio that corresponds to the viewing angle.

15. A method for using a laser to inscribe textual information at a surface of a substrate that is only viewable from a vantage point having an angular displacement that is other than ninety degrees (90°
- ) relative to the surface, the method comprising;
positioning a laser capable of projecting a laser beam towards the surface at the angular displacement; projecting the laser beam at the surface at the angular displacement; and causing the laser beam to impinge the substrate at the surface, wherein the laser beam inscribes the textual information at the surface by altering a reflective characteristic of the surface, wherein the textual information has an aspect ratio and a line width in accordance with the angular displacement. - View Dependent Claims (16, 17, 18, 19, 20)
