The invention relates to a radio frequency (RF) system and method for improving the detection efficiency of an identification system including a transponder and a reader. The system ( 1 ) comprises an interrogator reader device ( 3 ) having an interrogator coil antenna ( 4 ) and a transponder ( 2 ) having a transponder coil antenna ( 5 ) and a microchip ( 6 ) Advantageously, the interrogator reader device ( 3 ) comprises a detection portion ( 11 ) including a sensitive signal gain detector (SSGN) for detecting just the presence of the transponder coil antenna ( 5 ) in case of misplacement of the transponder or broken link between the transponder coil antenna ( 5 ) and the microchip ( 6 ). The invention allows remedying to those potentially dangerous situations that might lead to a misdetection of the transponder ( 2 ).
