Abstract: A composite image is generated from a decorative image, a bar code, and one or more filter patterns. The composite image visually approximates the decorative image, yet the composite is machine-readable by a scanner capable of reading the original bar code, and the composite encodes the same data as the original bar code. Filter patterns provide a flexible way to selectively alter the decorative image. Alterations can be applied only in locations where necessary, and only to the degree necessary, in order for the composite image to be recognized as a bar code. Alterations can also be applied in arbitrary color spaces, including human perceptual color spaces where brightness can be altered with less impact on apparent color.

Or it shows the number of votes for users who picked it with their phones. The barcode could show scrolling text. A barcode on a computer screen simulates a pushbutton; pressed when the user takes a photo of it with a cellphone. Suppose a barcode has a symbol drawn on its foreground rectangles, and the barcode encodes a URL. The URL is crafted to maximize the number of foreground rectangles that the symbol intersects, helping a human interpolate the symbol from fragments.

The invalidation is also visible to humans so that the consumer knows if the exposure occurs after purchase. Activation brings liquid from the first reservoir in contact with the migration medium. The liquid progressively produces a change in color over time in the migration medium. When the liquid has crossed the migration medium, it will come in contact with the absorptive medium. The absorptive medium will then rapidly change color.

Abstract: An additional layer of encoding is provided using conventional one-dimensional (“1-D”) bar code symbology. Dark bars of at least 2 heights are used (where the dark bars may be narrow or wide, and may be separated by a space that is narrow or wide) for 2-dimensional (“2-D”) encoding. Whereas the width of the dark bars is significant in the 1-D encoding, the height of the dark bars is significant for the 2-D encoding. In one approach, dark bars of a shortest height are used for encoding conventional 1-D data, while dark bars of other heights encode additional data in a 2-D portion of a bar code. In another approach, consecutive dark bars are used in combination, according to a mapping which correlates the various combinations of bar heights to respective characters. The 2-D encoding rules may be proprietary, providing a type of data privacy.

Even displays which have no backlight, for example but not limited to OLED and LED displays, may be used for light-simulated bar codes. While the entire display may be used, single pixels or pixel groups of the displays of such displays may be used.
