Access to predetermined Internet-based services or sites can also be had as an award to an individual for inputting an iconic code at a machine connected to the Internet if the input code tests as valid, with the code being marked so as to be usable only once. Preferably, the iconic code is input by click-selecting displayed icons one after another in an order that corresponds to that of a code provided to the individual. POS methods for code processing are also described.
