Method and associated device for providing and storing two-dimension code information, and associated device

The embodiment of the invention discloses a method and an associated device for providing and storing two-dimension code information, and the method and the device are used for limiting the use range of a two-dimension code. The method disclosed by the embodiment of the invention comprises the following steps of: receiving the information obtaining instruction sent by a two-dimension code information obtaining device, wherein the information obtaining instruction is used for obtaining data information corresponding to a target two-dimension code; and inquiring the use limit parameter of the target two-dimension code; and judging whether the information obtaining instruction meets requirements on the use limit parameter according to the information provided by the information obtaining instruction, and if so, providing the data information corresponding to the target two-dimension code for the two-dimension code information obtaining device.
