1. A method for retrieving and utilizing item information to perform a transaction, comprising;

  • detecting, by an item identification system associated with the data processing system, a presence of a item physically located within a detection field of the item identification system and providing, by the item identification system, an identification of the item to the data processing system, wherein the item is a physical item that is recognized by the item identification system;

    determining, by the data processing system, if valid item information for the item is present in a cache of the data processing system in response to detecting the item as being present in the detection field of the item identification system;

    retrieving, by the data processing system, the valid item information from the cache in response to the valid item information for the item being determined to be present in the cache of the data processing system;

    retrieving, by the data processing system, the valid item information from a remotely located cloud computing system in response to a determination that valid item information is not present in the cache; and

    performing, by the data processing system, the transaction based on the valid item information, wherein the detection field of the item identification system is located physically upstream on a path of motion of the item downstream towards a point of sale device, wherein the retrieval, by the data processing system, of the valid item information from the remotely located cloud computing system is performed prior to the item reaching the point of sale device, and wherein the performance of the transaction based on the valid item information is performed in response to a scanning of an item identifier of the item at the point of sale device and subsequent to retrieval of the valid item information from the remotely located cloud computing system.
