Portable mobile devices may have ambient light sensors (ALS) capable of modulating the level of backlight on the display of the portable electronic device in various environmental situations. The ALS is capable of receiving an infrared signal or a visible light signal that may then be read to determine an end and a beginning, and parsed to extract the code. The information sent from the infrared or visible light source to the portable electronic device may be handled by the device in various ways including direct processing and display to present the user of the portable electronic device with a coupon, offer, or other benefit. This may occur in several ways including displaying a coupon or an offer, launching a URL or URI, or launching an application on the portable electronic device. |

1. A method of one-way communication transmission, comprising:
sensing, by an ambient light sensor embedded in a mobile phone, a light event; determining, by the mobile phone, that the light event is a modulated light signal; in response to the determination that the light event is the modulated light signal, parsing, by the mobile phone, an output of the ambient light sensor including the modulated light signal to extract a uniform resource locator (URL) or a uniform resource identifier (URI); extracting, by the mobile phone, the URL or the URI from the modulated light signal based on the parsing; displaying, by the mobile phone, in response to the extracting, at least one benefit accessed based on the URL or the URI from at least one vendor of a plurality of vendors; subsequent to parsing the output of the ambient light sensor and extracting the URL or the URI, averaging, by the mobile phone, remaining raw sensor data of the output produced by the ambient light sensor; and adapting a display brightness of the mobile phone based on the averaged raw sensor data. |
