Abstract
The objective of the invention is to solve a problem that the safety is lower during merchandise anti-counterfeiting identification because some user mobile terminals do not have a function of RFID and just employ the two-dimensional code technology independently. In order to achieve the above purpose, the invention employs a technical scheme that the system comprises a system server, RFID electronic tags and two-dimensional codes which are disposed on all merchandises, or a random number generator. The system achieves the good combination of the technology of RFID anti-counterfeiting identification and the technology of two-dimensional code anti-counterfeiting identification. When the user mobile terminal does not support a function of RFID reading and writing, the system is compatible with a two-dimensional code anti-counterfeiting scheme with the lower safety. Because of the protection from a one-time one-card RFID high-safety system scheme and the convenience and popularization of the two-dimensional code scheme, the system gives full consideration to high safety and high universality.
