The invention discloses a method for carrying out the program consistency comparison of acquisition terminal software. The method comprises the following steps: setting up an acquisition platform, reading an acquisition terminal program, utilizing an encryption rule to encrypt the acquisition terminal program and a factory backup program, and carrying out comparison on the programs one by one. The method is convenient for the acquisition terminal to carry out detection after arrival of goods, guarantees the quality of a supply-of-material acquisition terminal and realizes the uniform supervision of the acquisition terminal software program. The method carries out comparison to determine the program consistency of the supply-of-material acquisition terminal and a detection acquisition terminal, realizes the automatic extraction of the acquisition terminal software program, and carries out a software comparison function.
