The invention discloses a paper verifying device and method for an intelligent waste paper recycling system and relates to the technical field of waste paper recycling devices. The device includes a real-time verifying assembly and a later-stage reverifying assembly. The real-time verifying assembly includes an image acquisition and recognition module which acquires the image information of articles put into a waste paper recycling box, compares the image information with reference pictures in a database and outputs image recognition result information of different levels; the later-stage reverifying assembly comprises a user information storage module and a transaction information storage module, and image acquisition information, user account information and user transaction informationare correspondingly stored one to one; a later-stage comparison module is used for obtaining and outputting comparison result information through manual comparison when waste paper is recycled; through combination of image recognition and various detection modes, whether or not the articles put into the waste paper recycling box meet the recycling requirements is recognized quickly and effectively, the efficiency of verifying the waste paper is improved, and the loss of operators caused by misjudgment on the types of the articles in the waste paper recycling box is reduced.
