Barcode reading system including a sled reader and relay application

A barcode reading system for a mobile device, the barcode reading system including:

• a barcode sled reader configured to connect to the mobile device, the barcode sled reader including:
• a barcode reader configured to generate image data of a barcode;
• and
• a decoding processor configured to receive the image data from the barcode reader, decode the image data, and send the decoded image data to the mobile device;
• a relay application stored on a non-transitory computer readable medium of the mobile device and executed by a processor of the mobile device;
• a tool application executed by a processor of an intermediary device and in communication with a legacy system, wherein:
• the relay application and the tool application are each configured to perform a Transmission Control Protocol (TCP) to establish and maintain a TCP/Internet Protocol (IP) connection there-between over an IP network for transport of decoded image data provided by the barcode sled reader;
• the relay application is configured to:
• each time it receives decoded image data from the barcode sled reader forward the decoded image data to the tool application via the TCP/IP connection;
• and
• the tool application is configured to receive the decoded image data from the relay application via the TCP/IP connection and provide the decoded image data to the legacy system via a transport distinct from the TCP/IP connection.
