The present invention discloses a method and device for communication module detection based on the bar codes and the RFID. The method comprises: obtaining the bar-code data of a communication module and the RFID label data of a tray on a detected flow line, wherein the tray is configured to carry one or more than one communication modules to generate a first control command for matching the bar-code data and the RFID label data; and matching the bar-code data and the RFID label data according to the first control command, and obtaining first matching information. The technical problem is solved that the artificial detection communication module is low in efficiency in the prior art.
