Information obtaining method and apparatus
Various embodiments provide methods, apparatus, and electronic devices for information obtaining, information management and 2D barcode generation. In an exemplary method implemented by an electronic device, a first two-dimensional (2D) barcode can be obtained. An image transformation can be performed on the first 2D barcode to obtain a virtual 2D barcode. Further, according to validity of the virtual 2D barcode, relationship information of the first 2D barcode can be obtained based on a mapping relationship of the virtual 2D barcode in a database.
