Radio Frequency Identification

Radio Frequency Identification (RFID) is a wireless technology that uses electromagnetic fields to automatically identify and track tags attached to objects. The system consists of RFID tags (which store data) and RFID readers (which wirelessly read the tags), enabling contactless data transmission. It is widely used for inventory management, access control, and supply chain logistics.

Also known as: RFID, Radio Frequency ID, RFID Technology, RFID Systems, RFID Tagging

Why learn Radio Frequency Identification?

Developers should learn RFID when building systems for asset tracking, inventory automation, or secure access control, as it provides real-time data without line-of-sight requirements. It is particularly useful in retail, healthcare, and logistics applications where efficient object identification is critical.
