Design of bar code automatic identification system based on mobile terminal

This paper studies the problem of automatic identification of bar code in agricultural product tracing, because the protection of special products of agricultural products is conducive to the poverty alleviation of agricultural products and the increase of farmers' income. In agricultural product traceability, what method is used. Firstly, the advantages of EAN / ucc-128 bar code are analyzed, and the characteristics of the mobile terminal in the bar code automatic recognition system are studied. Research shows that fast scanning barcode can reduce the storage space and identification time. Therefore, this automatic recognition system is very applicable in the actual process.
