An Introduction to Passive RFID

Throughout the manufacturing, logistics, and perishable food industries, Radio Frequency Identification (RFID) technologies enable asset tracking, streamline the supply chain, and help improve operational efficiency. RFID is an automatic identification technology that relies on Radio Frequency (RF) waves to read encoded digital data. RFID is similar to bar code technology in concept. However, reading a bar code requires a line of sight optical scan. RFID does not require a visible tag or label to read its stored data - a powerful benefit unmatched by any other technology today.
