Abstract
An encoded data pattern touchscreen sensing system includes an encoded data pattern including one or more electrical materials arranged in a pattern representative of data. The encoded data pattern touchscreen sensing system further includes an encoded data pattern touchscreen sensing computing device including: a touchscreen, a plurality of electrodes integrated into the touchscreen, and a plurality of drive-sense circuits coupled to the plurality of electrodes, where, when in close proximity to the encoded data pattern, the plurality of drive-sense circuits detect changes in electrical characteristics of the plurality of electrodes caused by the encoded data pattern. The encoded data pattern touchscreen sensing computing device further includes a processing module operably coupled to: receive a set of detected changes in electrical characteristics, interpret the detected changes as a set of impedance values representative of the one or more electrical materials of the encoded data pattern, and interpret the set of impedance values to determine the data.
