A data decoding system can comprise one or more computers communicatively coupled to a network. The computers can execute at least one decoding process. The decoding process can be configured, responsive to receiving a decoding request comprising an image of decodable indicia, to locate the decodable indicia within the image, and to decode the decodable indicia into a decoded message. The decoding process can be further configured, responsive to completing a decoding operation, to transmit to the client the decoded message and/or the decoding operation completion code.
