Zusammenfassung:	The invention discloses a two-dimensional code validity control method, and the two-dimensional code validity control method comprises the following steps: receiving a customer operation carrying thebiological information features and operation information of a customer through a man-machine interaction interface, and judging whether the customer operation is legal or not; if so, generating two-dimensional code associated information; generating a two-dimensional code according to the two-dimensional code associated information, wherein the two-dimensional code is associated with a two-dimensional code unique identifier and the two-dimensional code associated information, AND the two-dimensional code unique identifier is a combination of a timestamp and a random number; and counting the number of scanning times of the two-dimensional code, and when the number of scanning times of the two-dimensional code is equal to the preset maximum number of scanning times, identifying the two-dimensional code as a failed
