Multi-card identification anti-collision method and device

The invention relates to the technical field of electronic communication, and particularly relates to a multi-card identification anti-collision method. Digit information of each radio frequency card digital identifier is read and recorded, read-write operation is performed on radio frequency cards corresponding to the digit information having uniqueness, and the radio frequency card suitable for the current scene can be rapidly found through simple screening. If all the radio frequency cards corresponding to the digit information having uniqueness do not meet the task requirements issued by a reader, the radio frequency cards can be screened and ordered according to the digital identifier of each radio frequency card and the digit information thereof, and read-write operation is performed on the first radio frequency card after screening and ordering so that the situation of leak reading and failure of identification when the reader receives multiple radio frequency card signals can be effectively avoided. According to the multi-card identification anti-collision method, a function module frame can be formed by establishing function modules, and implementation can be performed by computer programs stored in a computer readable storage medium.
