  If you’ve ever held a plastic access card, a warehouse tag, or a library label and wondered   “Is this an RFID tag, and what type is it?” , you’re not alone. RFID technology hides in plain sight — inside cards, stickers, and even tools — and it comes in several different types. Knowing how to identify your   RFID tag   can save hours of trial and error, especially if you’re troubleshooting or planning to integrate it into a new system. Step 1: Look for Clues on the Tag or Card Sometimes the answer is right in front of you. Check the surface of the card or packaging — you might find a small print like  “13.56 MHz” ,  “125 kHz” , or  “UHF” . These numbers tell you the operating frequency: 125 kHz (LF)  – often used for access control or animal tracking 13.56 MHz (HF/NFC)  – found in transport cards, ID cards, and smartphones 860–960 MHz (UHF)  – used in logistics, inventory, or vehicle management If nothing is printed, don’t worry — ther...

If you’ve ever walked through a warehouse where items move faster than people can count, or managed an industrial site where assets vanish unless someone’s watching 24/7 — then you already understand the pain that  ultra high frequency RFID  quietly solves every day. In the RFID industry, there’s a simple rule:  the higher the frequency, the farther you can see — and the more precise you need to be.  UHF, or ultra high frequency RFID, operates roughly between  860 MHz and 960 MHz , and it’s what makes large-scale, automated identification possible. But the technology itself isn’t “magic.” It’s the result of years of antenna design, signal tuning, and practical problem-solving done by integrators and engineers who’ve had to make it work in the real world. The Core Idea Behind UHF RFID Every UHF RFID system is built around the same three pieces:  a tag, a reader, and the software that connects them. The tag carries a small chip and an antenna. When the reader...

  Let’s be honest — UHF RFID technology isn’t new anymore, but it’s still one of those tools that quietly keep operations running smoother, especially in logistics, warehousing, and large-scale asset tracking. And for anyone working in RFID integration or solution design, knowing your way around a  UHF RFID Sled Reader  can make you look a lot smarter in front of clients. So, What Exactly Is a UHF RFID Sled Reader? Think of it as a smart add-on for your phone or tablet. You slide your mobile device into the reader — it clicks in snugly — and suddenly your phone becomes a serious  RFID scanner . The sled itself houses the  antenna, handle, and power source , while your phone handles the brains — data processing, connectivity, and interface. Most sled readers connect via  Bluetooth or USB , depending on what the user prefers. Once paired, it can start reading hundreds (sometimes thousands) of tags per second. For teams in warehouses, retail stores, or hospita...
