RFID (Radio-Frequency Identification) technology uses electromagnetic fields to automatically identify and track tags attached to objects. RFID is widely used in various industries, including retail for inventory management, logistics for tracking shipments, and healthcare for monitoring equipment and medication and a large number of other industries and domains. Its advantages include improved accuracy, speed, and the ability to read multiple tags simultaneously without direct line-of-sight. An RFID system typically consists of three components:
1. **RFID Tags**: These contain a microchip and an antenna. The chip stores information about the item, while the antenna enables communication with an RFID reader.
2. **RFID Readers**: These devices emit radio waves to communicate with the tags. They receive information from the tags and can process or relay it to a computer system.
3. **Backend System**: This includes software that manages the data collected from the readers, allowing for tracking, inventory management, and other applications.
The future of RFID (Radio Frequency Identification) technology looks promising, with advancements and applications expanding across various domains.
