Title
Caching Item Information in a Cloud-Based Point of Sale System
Abstract
Mechanisms are provided, in a data processing system, for retrieving and utilizing item information to perform a transaction. The mechanisms receive an identification of an item present in a detection field of the item identification system. A determination is made as to whether 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. If valid item information is present in the cache, the valid item information is retrieved from the cache. If valid item information is not present in the cache, the valid item information is retrieved from a remotely located cloud computing system. The transaction is performed based on the valid item information.
