From intelligent access control to automated parking systems, UHF RFID technology is becoming a vital component of modern IoT ecosystems. YANZEO’s SR791 RFID Reader stands out with its extended read range, robust build, and versatile connectivity. Let’s take a closer look at how this device works—and where it fits into next-gen automation.
1. RFID Technology in Action
Radio Frequency Identification (RFID) enables seamless, wireless data exchange using electromagnetic waves. At the core, it consists of:
RFID Tags – Small chips that carry data, activated by reader signals
Readers (like SR791) – Emit RF signals and collect tag information
Backend Systems – Store, analyze, and use the data for real-time decisions
Compared to traditional barcodes, RFID offers:
Greater efficiency – Read multiple tags at once, even without direct line-of-sight
Longer range – Detect passive tags from several meters away
Tougher performance – Designed for challenging environments
