Abstract
The current disclosure extends to normalizing UPCs so the normalized UPCs can be readily compared against each other and used for item lookups in a local cache. Embodiments of the present disclosure include a UPC cache on a user's mobile device, such as a smartphone. In such embodiments, a UPC that is normalized following processes set forth in the present disclosure may act as a cache key for related product information stored in the cache. By conducting item lookups in a local cache, requests for that data can be served faster than if the data were stored on a remote server.
