Abstract: A system and a method for improving the reading range of RFID tags and detecting objects without placing RFID tags on them, through placement of the tags in optimal positions with respect to other elements responsive to electromagnetic waves that are naturally present in the environment of use of the RFID tags. RFID tags are placed in optimal positions with respect to metal surfaces on an object to be detected to enhance their readability based on reflective contributions of the RFID signal from the metal surfaces. Detection of objects possessing metal surfaces without RFID tags placed on them are achieved by placing an RFID tag behind a reader in a reader assembly and relying on the RF energy reflected from the metal surface of the object.
