Jan 15, 2026LF vs HF vs UHF RFID: Differences, Ranges, Use Cases, Pros/Cons & How to Choose
RFID is often grouped into three main frequency families: LF (Low Frequency), HF (High Frequency), and UHF (Ultra-High Frequency). Picking the right band is one of the biggest decisions in any RFID project because it affects read range, speed, tag cost, phone compatibility, performance near metal/liquids, and system architecture. This guide compares LF vs HF vs UHF in a practical way […]

Near-Field Coupling in RFID: What It Means, How It Works, and Why It Matters
Near-field coupling is the communication method used by LF (125/134 kHz) and HF (13.56 MHz, including NFC) RFID systems. Instead of “radiating” like a long-range radio link, near-field RFID works more like a transformer: a reader coil creates a magnetic field, and the tag coil couples to that field to power up and exchange data. This is why LF/HF/NFC are typically short-range, […]

What Is RFID? How RFID Works, Types (LF/HF/NFC/UHF), Applications, Pros/Cons & Buyer Guide
RFID—Radio Frequency Identification—is a wireless technology that identifies objects using radio waves. An RFID system can detect items without line-of-sight, often in bulk, and can automate tracking across warehouses, factories, retail stores, hospitals, and security systems. This guide explains what RFID is, how it works, RFID frequencies (LF/HF/NFC/UHF/RAIN), tags and readers, passive vs active vs […]

Passive RFID vs Active RFID: Differences, Pros/Cons, Use Cases & How to Choose
RFID systems generally fall into two big tag categories: passive RFID and active RFID. They solve different problems. If you choose the wrong one, you’ll either overpay (active when passive is enough) or underperform (passive when you truly need real-time long-range visibility). This guide explains the differences in plain English, with practical selection criteria and […]

RFID Tags: The Complete Guide (Types, Frequencies, Memory, Use Cases & How to Choose)
RFID tags are small devices (a chip + antenna) that store an ID (and sometimes more data) and communicate wirelessly with an RFID reader. They’re used to identify, track, and manage items in warehousing, retail, manufacturing (WIP), healthcare, asset tracking, access control, and logistics—often faster and with less manual work than barcodes. This guide explains […]
