Challenges of Radio Frequency Identification Technique

In recent years, there have been rise in the number of applications based on Radio Frequency Identification (RFID) systems and have been successfully applied to different areas as diverse as transportation, health-care, agriculture, and hospitality industry to name a few. RFID technology facilitates automatic wireless identification using electronic passive and active tags with suitable readers [1]. Initially RFID tags were developed to eventually replace bar codes in supply chains. Their advantages are that they can be read wirelessly and without line of sight, contain more information than barcodes, and are more robust [2]. The paper describes the current technology, including the frequency ranges used and standards [2].
