Systems, methods and computer programs provide for implementing a mobile communication device, such as a smart telephone or the like, as a point of transaction for in-store purchases, such that all a customer needs to do is capture the coded indicia of products they desire (i.e., scan the products) with their mobile communication device as they shop and the purchase transaction will subsequently occur based on either the customer (in possession of the mobile communication device) being physically located in a designated area of the store or the lapse of a predetermined period of time from when the coded indicia was captured.
