RFID Guides
In-depth technical guides that explain how RFID technology works – from the physics of radio-frequency communication to the data structures encoded on every tag.
What is RFID?
A complete guide to radio-frequency identification – how it works, frequency bands, tag types, standards, and real-world applications across every industry.
FundamentalsInductive Coupling
How LF and HF RFID systems transfer energy and data using magnetic fields – the physics behind every access card tap, pet microchip scan, and contactless payment.
FundamentalsBackscatter Coupling
How UHF RFID tags communicate over metres by reflecting the reader's signal – the mechanism behind supply chain tracking, retail inventory, and warehouse automation.
FundamentalsEPC Encoding Explained
How barcodes become RFID tags. Walk through the full encoding pipeline from GTIN barcode to EPC binary, with interactive bit-field diagrams for every scheme.
FundamentalsReed-Solomon Error Correction
The mathematics behind QR codes, GS1 DataMatrix, and RFID data integrity. Galois fields, generator polynomials, and worked examples.
