Abstract

A method for scanning multiple barcodes is provided. A tag template, recording a predetermined number of barcode forms and relative configuration orientations of the predetermined number of barcode forms, is read. The tag is photographed to obtain a tag image of the tag, wherein a surface of the tag includes a plurality of barcodes.
