An encoded image may be captured by a camera to produce particular information from a display that cannot be deciphered by a human eye (e.g., a quick response code a.k.a. a QR code). The encoded image can be decoded and then the information contained therein can be acted upon by a user device, such as a mobile phone device. The user may be prompted for additional information, redirected to a particular website, sent to a specific web application or online authentication portal, etc. A service provider computer system may also perform processing on information gleaned from the encoded image, and provide information regarding the subsequent outcome of the processing to a user.
