The present invention relates to a radio frequency identification (RFID) device and method for book tagging, using which a RFID tag which is designed to attach to a book is first being scanned and detected in view of optimizing the RFID tag's signal strength and its effective reading rate as well so as to determine a position on the book for the RFID tag to attach thereat while allowing the detection to the RFID tag to be prevented from being adversely affected by metals or magnetic materials that are situated ambient to the book.
