The RFID system is for automatic recognition of one or all of a plurality of objects or articles located in an interrogation zone and having RFID tags mounted thereon. The tags have transponders carrying RFID information codes are sequentially and individually scanned with interrogation signals and activated to emit the information codes signals readable with a reader. The interrogation signals are based on the reader antennas and the configurations and locations of the tags. Signals returned from the transponders of the tags are processed to determine their electronic product code and location. The operation is repeated until the recognition and location of all tags in the entire interrogation zone are completed.
