  • Graphic two-dimensional barcode and creating method thereof
    Patent number: 10621482
    Abstract: A method of creating a graphic Quick Response (QR) code includes a picture and first and second two-dimensional barcodes combined through a halftoning technique. The graphic QR code includes a plurality of module units, each having a plurality of sub-modules. Information dots containing first information for the first two-dimensional barcode are provided, and each of the information dots of the first two-dimensional barcode is located at a central sub-module of each of the module units. The first information is readable by a scanning device. Information dots containing second information for the second two-dimensional barcode are provided, and each of the information dots of the second two-dimensional barcode is located at one of the other sub-modules. A position of each of the information dots of the second two-dimensional barcode is capable of being located by inputting a key through a decryption program for obtaining the second information.
