Rfid recognition system and method

PURPOSE: Radio frequency identification (RFID) recognition correction system and recognition correction method are provided to judge an RFID recognition error by photographing a product having an RFID tag and confirming the number of products through RFID tag recognition with image analysis. CONSTITUTION: An RFID reader unit (20) recognizes RFID tag information of a product and an image photography unit (40) photographs the exterior of the product. A correction analysis server (100) analyzes an image obtained from the image photography unit, calculates the number of products and compares the number of the products with the number of the tag information recognized in the RFID reader unit. When the number of the products and the number of the tag information are not coincided with each other, the correction analysis server generates antenna output intensity of the RFID reader unit and correction information of a product image photography direction and requests RFID tag recognition and product image recognition again.
