A method for anonymous processing of a purchasing request. Initially, a text message comprising the purchasing request is received, by a processing platform, from a mobile phone. A current authorization code comprising a random number is generated in response, and then sent, via a text message, to the mobile phone. A merchant is provided with a pending authorization code, who then sends a communication including the pending authorization code to the platform. The purchasing request is validated in part by determining whether the pending authorization code is identical to the current authorization code.
