14 Claims

1. An authentication method comprising:

sensing an electrically conductive ink in proximity to a computing device, the computing device including a capacitive pad having one or more sensors, the electrically conductive ink being printed on a surface of a product;

sensing a desired pattern of the electrically conductive ink using the one or more sensors of the capacitive pad;

initiating an internet browsing application running on the computing device in response to triggering appropriate sensors of the one or more sensors of the capacitive pad;

receiving a package code from the computing device;

determining whether the package code is present in a non-transitory computer readable medium; and

providing the computing device with access to information if the package code is present in the non-transitory computer readable medium.
