Customizing the Decoder
According to the scan environment and the bar code printed material’s quality, the decoder can be
customized to efficiently improve scanning performance. First, to maintain scanning performance
with the normal decoding logic, perform decoding using with the decoder and if it does not
succeed the decoding, customize it so that the decoding can be performed for a better scanning
performance.
