RFID Tags

RFID (Radio Frequency Identification) tags are small devices that use radio waves to automatically identify and track objects or people. Each tag contains a tiny chip with a unique code and an antenna to communicate with a reader device. When the reader sends out radio signals, the tag responds by transmitting its data. This technology is used in various applications like inventory management, access control, and contactless payments, providing a quick, contactless way to gather information without needing direct line-of-sight or manual input.
