1. A transaction method using virtual code, the method comprising:
receiving, by a virtual code verification device, via a wireless communication, from a virtual code generation device, a virtual code, which is generated by a virtual code generation function included in the virtual code generation device, wherein the virtual code verification device and the virtual code generation device are connected via the wireless communication;
searching, by the virtual code verification device, for a storage location of a User Identification (UID) in the virtual code, wherein the storage location indicates a point on a track of a storage location search algorithm, and the point corresponds to a time point when a user requests a registration of the UID;
searching, by the virtual code verification device, for control command information stored in memory of the virtual code verification device by matching with the UID;
performing a control command based on the control command information;
storing a plurality of UIDs in the memory of the virtual code verification device and also in memory of the virtual code generation device;
matching the control command information with a first UID of the plurality of UIDs during a first preset period; and
changing the control information to be matched with a second UID of the plurality of UIDs during a second preset period.
