Abstract
An electronic device may include a housing, a display positioned at least partially within the housing, a cover assembly coupled to the housing and comprising a chemically strengthened glass member, and an encoded marking formed within the chemically strengthened glass member between an upper surface and a lower surface of the chemically strengthened glass member. The encoded marking may include an array of marks, each mark of the array of marks having a dimension between about 3 microns and about 10 microns and set apart from an adjacent mark by an unmarked area of the chemically strengthened glass member. Each mark may represent a bit of information in a binary number system. The encoded marking may be readable, by an optical magnification apparatus, through the upper surface.
