Abstract
The present invention provides systems and methods capable of collecting and analyzing a multi-fields two-dimensional code. A computer-implemented method of analyzing multi-fields two-dimensional code, comprises: receiving decoded multi-fields two dimensional code; identifying a first field and a second field from the decoded multi-fields two dimensional code; and determining whether the first field of the multi-fields two-dimensional code matches one of multiple pieces of pre-stored first information and whether the second field of the multi-fields two-dimensional code has ever been collected before, for providing a result with respect to the decoded multi-fields two dimensional code.
