Abstract: A system for using machine-readable indicia to provide additional information and offers to potential customers, the system comprising a network-connected server adapted to receive coded information from mobile devices, a database coupled to the server and containing data pertaining to products, a software application executing on the server for processing the coded information, and a plurality of labels containing machine-readable indicia and posted near products for sale, is disclosed. According to the invention, on receiving coded information from a mobile device, the server provides the data to the software application, and the software application determines from the coded information a location from which the information was obtained and a product to which the information pertains, and, based at least in part on the location and product information obtained, the application obtains additional data from the database and sends it to the mobile device from which the coded information was received.

Abstract: A method and apparatus for payment with mobile device at point of sale (POS) terminal are proposed, where said apparatus is comprised of a microprocessor which connects to POS terminal as a payment console and communicates with said POS terminal via protocols developed for payment consoles; said apparatus also has an additional connection to internet via which the apparatus communicates with services supporting its function. The mobile device operated by a user captures a public token exposed by said POS terminal and communicates with the supporting internet services, which validate said mobile device, authenticate the mobile device owner, validate the POS terminal, and establish link between said mobile device and said apparatus.
