A barcode recognition method is provided for recognizing a barcode to derive effective barcode information thereof. The barcode includes a plurality of segments. In the method, every time the barcode is scanned and recognized, any segment, in which a barcode information fragment carried therein is able to be derived, is recorded as an effective segment. And then the effective segments are selected and combined to generate a plurality of segment combinations. The information carried by the segment combinations is respectively verified by the checksum thereof, so as to find out the segment combination, which is successfully verified by the checksum thereof, to be the effective combination. Every time the barcode is scanned and recognized, only part of the segments of the barcode has to be successfully recognized, and the effective segments derived are combined and verified, so as to quickly recognize the barcode.
