Feb 14, 2026Long Distance RFID Reader: Real-World Read Range, How to Choose, and How to Get Reliable Long-Range Performance
What is a “long distance” RFID reader? In most industrial and logistics projects, “long distance RFID reader” usually means a UHF (RAIN RFID) reader designed to read passive UHF tags at longer distances than LF/HF systems. UHF (typically 860–960 MHz depending on region) is commonly chosen for fast inventory and longer range performance. Important reality check: “Long distance” is not […]

OEM Meaning (What It Stands For, How It Works, and OEM vs ODM vs Aftermarket)
What does OEM mean? OEM most commonly stands for Original Equipment Manufacturer. In business and manufacturing, an OEM is a company that makes a component, subsystem, or product that another company sells (often under its own brand)—or incorporates into a finished product sold to end customers. The key idea OEM describes a role in the supply chain: Investopedia frames […]

HF RFID Standards (13.56 MHz): A Practical Guide to ISO 14443, ISO 15693, ISO 18000-3, NFC, and EMV
HF RFID runs at 13.56 MHz and is widely used for access control badges, contactless payments, libraries, healthcare wristbands, and NFC phone tap experiences. When people say “HF RFID,” they often mean very different things—because HF is a frequency band, while standards define the protocol stack (how tags and readers actually communicate). More about HF […]

Passive RFID Tags: What They Are, How They Work, Types, Use Cases, Pros/Cons & Buying Guide
A passive RFID tag is the most common RFID tag type in the world. It has no battery. Instead, it is powered by the electromagnetic field generated by an RFID reader. Passive tags are the foundation of RAIN UHF RFID item labeling (retail, logistics), HF/NFC access cards and smart labels, and many LF identification systems. This guide explains what passive tags are, how they work, the differences […]

HF RFID (13.56 MHz) Explained: How It Works, Standards, Use Cases, Pros/Cons & Selection Guide
HF RFID (High-Frequency Radio Frequency Identification) is a widely used RFID technology operating at 13.56 MHz. It’s best known for short-range, controlled reads, strong support for secure credentials, and the fact that NFC is built on the same HF band. If your project needs a tap / close-range user experience—like access control badges, library book tags, healthcare wristbands, or secure ID cards—HF […]

LF 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 […]
