Systems and methods are disclosed for communicating product or service information to a potential purchaser. A product or item describing a service are scanned to obtain both a product or service code and an advertisement promotion code provided by a vendor/retailer or manufacturer of the product or service using a smartphone of a first user. A barcode is generated on the smartphone by combining the product or service code and the advertisement promotion code with information from the smartphone associated with the product or service and with an advertiser code that uniquely identifies the first user. The barcode is communicated to a communication device of a second user that is the potential purchaser of the product or service. When the communication device is presented to a point of sale (POS) terminal, the terminal scans the barcode, decodes the barcode, and compensates the first user according to the advertisement promotion code.
