Feb 28, 2026RFID Read and Write: How RFID Data Is Read, Written, Locked, and Verified in Real Deployments
In RFID systems, read means the reader detects a tag and retrieves data from its memory. Write means the reader changes data stored on the tag (for example, writing a new EPC or user data), sometimes followed by locking that data to prevent future changes. Most commercial RFID deployments use UHF (RAIN RFID) for longer range and fast bulk scanning. The core air-interface […]

LLRP / ALE / EPCIS: The RFID Software Standards That Turn Raw Reads Into Business Events
What are LLRP, ALE, and EPCIS (in one minute)? These three GS1/EPCglobal standards cover different layers of an RFID solution: A helpful mental model is: LLRP = control readers → ALE = filter/shape reads → EPCIS = share business events Where they fit in an RFID architecture GS1’s architecture discussions describe that when ALE and LLRP […]

RFID Software: What It Is, How It Works, Architecture, Standards (LLRP/EPCIS/ALE), and How to Choose the Right Stack
What is RFID software? RFID software is the layer that turns RFID hardware signals (readers, antennas, tags, sensors) into usable data and workflows—inventory updates, asset movements, shipping/receiving events, access logs, and analytics. In most real deployments, RFID systems require middleware: software that sits between RFID interrogators (readers) and enterprise applications (WMS/ERP/MES/POS). It manages/configures devices and processes raw tag data by filtering duplicates […]

RFID Chip: What It Is, How It Works, Memory Banks, Types, and How to Choose the Right One
What is an RFID chip? An RFID chip is a small integrated circuit (IC) used in radio-frequency identification systems to store an identifier and/or data and communicate wirelessly with an RFID reader. In everyday conversations, “RFID chip” can mean two different things: Most people searching “rfid chip” are talking about the tag chip (the one […]

Handheld Barcode Scanner: Types, Features, and How to Choose the Right One
What is a handheld barcode scanner? A handheld barcode scanner (also called a barcode reader) is an optical device that reads printed (or on-screen) barcodes and sends the decoded data to a computer, POS system, mobile device, or industrial controller. Typical scanners include a light source, optics/sensor, and decoder circuitry to interpret the barcode pattern and output the […]

Long 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 […]
