Abstract
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.
