In modern transportation, efficiency is paramount, and RFID windshield tags are revolutionizing toll collection. One of the standout solutions in this space is FASTag, managed by the National Highway Authority of India (NHAI). FASTag leverages advanced Radio Frequency Identification (RFID) technology to facilitate seamless toll payments without requiring vehicles to stop or queue at toll plazas. Mounted on the windscreen of vehicles, FASTag operates by automatically scanning the RFID tag as the vehicle approaches the toll booth. Payments are then processed directly from the vehicle's linked account—be it a current, savings, or prepaid account—ensuring a swift and convenient transaction. Since FASTag became mandatory across India on December 15, 2019, the system has seen substantial adoption, with approximately 80 million FASTags issued to date. Each FASTag is equipped with tamper-proof technology, assigned a unique identifier, and securely affixed to the windscreen of each veh

The implementation of radio-frequency identification (RFID) technology has greatly transformed inventory management, asset tracking, and various other applications across industries. However, the presence of metals and liquids poses significant challenges to RFID performance due to interference and signal attenuation. Overcoming these challenges is crucial to fully leveraging RFID's potential. The Challenge of Metals and Liquids Metals and liquids reflect and absorb radio waves, which can cause interference and drastically reduce the read range and accuracy of RFID systems. In retail, manufacturing, and logistics, where metal shelves, containers, and liquid products are common, this can lead to significant operational inefficiencies. Without proper mitigation, the interference can result in misreads, missed reads, and a general decline in system reliability. Innovative Solutions for Metals To address the challenges posed by metal interference, several innovative solutions have been
