A processor is operably coupled to the first display and to the second electronic paper display. A wireless receiver is coupled to the processor for receiving data comprising, for example, an electronic ticket having a scannable optical indicia, and the processor and the second electronic paper display are operable to display of the optically scannable indicia on the electronic paper display. The second electronic paper display is operable to display the optically scannable indicia such as a barcode with at least one of a lower reflectance, a higher resolution, and a higher contrast compared to display of the optically scannable indicia on the first display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices having an auxiliary electronic paper display for displaying optically scannable indica","description":"A portable electronic device includes a housing, a first display operably coupled to the housing, and a second display comprising an electronic paper display operably coupled to the housing.
