ABSTRACT:
A machine readable symbol includes a data field of arranged data cells. Each data cell is assigned a data pattern value or a finder pattern value. Preferably, at least some of the data cells, or even all of the data cells, include at least one data pattern value and a finder pattern value which are overlapping. A color corresponding to the data pattern value, finder pattern value, or overlapping data pattern value and finder pattern value is assigned to each data cell. A finder pattern is discernable when the symbol is placed under a first color filter, or exposed to a first color, or the symbol image is processed by a first software color filter of an electronic device. A data pattern is discernable when the symbol is placed under a second color filter, or exposed to a second color, or the symbol image is processed by a second software color filter.
