Abstract:
1. A method of processing data strings, said method comprising the steps of: providing a buffer within an on-board memory of an electronic card, wherein said electronic card comprises a card portion including one or more user interface elements formed on a surface thereof, wherein said card portion is formed to enable said electronic card to be inserted into a reading device to facilitate reading of said electronic card and selection of said user interface elements, wherein said electronic card further comprises a processor coupled to said memory, and wherein said memory has retained therein at least a plurality of data strings each associated with a corresponding one of said user interface elements; storing identifiers within said buffer, wherein the identifiers identify selected ones of said user interface elements, wherein said identifiers are stored within said buffer upon selection of said selected ones of said user interface elements of said card using said reading device, and wherein one of said identifiers maps to a first data string and another of said identifiers maps to a second data string; retrieving said first and second data strings utilizing said identifiers stored in said buffer, wherein the retrieved first and second data strings are concatenated and stored in said buffer in place of said identifiers; and processing the concatenated first and second stored data strings using said processor.
