RFID knowledge
Understanding RFID. Make better decisions.
35 basic articles for retail, IT, operations and purchasing: from RFID basics to standards and hardware to pilot planning, business cases and retail processes.
Learning Paths
From the concept to a reliable RFID decision.
The knowledge area is structured as a decision-making process: first understand the basics, then classify technology, evaluate retail processes and finally prepare the pilot, business case and product selection.
Basics & Standards
Terms, frequencies, RAIN RFID, EPC, GS1 and EPCIS as a foundation.
Technology & components
Readers, antennas, range, material, encoding and source tagging.
Retail processes
Store, inventory, replenishment, omnichannel, DC, loss prevention and self-checkout.
Selection, Pilot & Industries
Label selection, pilot, business case, data protection, fashion, beauty and food.
All basic articles
35 items for RFID projects in stores.
What is RFID? A simple introduction to trading
RFID makes items identifiable without contact. This basic article explains the technology without any technical baggage and shows why it is becoming relevant in retail.
How does RFID work? Tag, reader, antenna and software explained
RFID seems simple if you understand the building blocks. This article explains how a radio reading becomes an operational decision.
RFID vs. Barcode: What is the difference?
The barcode remains important. RFID expands commerce where contactless capture, item visibility and process speed are needed.
RFID vs. NFC: What’s the difference?
NFC and RFID are often confused. This article explains when which technology makes sense.
RAIN RFID simply explained
RAIN RFID is the central RFID technology for many retail applications. This article explains the basics.
RFID frequencies: LF, HF, NFC and UHF at a glance
Not all RFID is the same. Frequencies determine range, application, hardware and process logic.
RFID tag, transponder, inlay and label: the terms simply explained
RFID terms are often mixed up. This article explains the most important differences for purchasing, IT and store operations.
Passive, active and semi-passive RFID tags: What retailers should know
Passive RFID tags are usually relevant in retail. Nevertheless, it is worth taking a look at the differences.
EPC simply explained: The digital key for RFID items
The EPC connects the physical item to the digital record. Without clear identification, RFID remains limited.
GS1 and RFID: Why standards make rollouts easier
RFID will only become scalable when data is understood across systems, suppliers and countries.
EPCIS explained simply: RFID readings become event data
EPCIS turns individual RFID readings into structured process events for supply chain, traceability and omnichannel.
RFID reader simply explained: handheld, stationary or gate?
The reader decides how RFID is used in the process. This article explains the most important reader types.
RFID antennas and reading zones: Why control is more important than range
RFID success depends heavily on where it is read – and where it is deliberately not read.
RFID reading range: What is realistic and what is not
Read range is important, but it depends on the product, tag, reader, antenna and environment.
RFID and material: correctly evaluate metal, liquid and packaging
Not every product is equally easy to tag. Material and packaging are crucial to RFID success.
RFID encoding: What belongs on the tag and what goes into the backend
RFID encoding decides whether a tag just works or really fits into business processes.
Source tagging explained simply
Source tagging moves tagging from the store to the source of the supply chain, making rollouts more scalable.
RFID in the store: Which processes benefit first?
RFID in the store becomes powerful when item data creates concrete tasks for teams.
RFID inventory: counting faster is just the beginning
RFID can speed up inventory. The greater benefit comes when regular inventory review improves operational decisions.
Inventory accuracy with RFID: Why system inventory and reality often diverge
Inventory accuracy is not inventory detail. It is the basis for product availability, omnichannel and store operations.
Replenishment with RFID: From the warehouse to the field faster
RFID helps turn refills from a gut feeling into a data-based task.
RFID and Omnichannel: Why reliable store stocks are crucial
Omnichannel doesn’t just depend on digital systems. It depends on physical inventory reality.
Click & Collect with RFID: Fewer searches, fewer cancellations
Click & Collect only works if available goods can be found.
RFID in incoming and outgoing goods
RFID can make goods movements at critical transfer points more visible.
RFID in the distribution center: Why DC processes influence store success
RFID in the store is only as strong as the quality of goods and data coming from the DC.
RFID and Loss Prevention: From Alarm to Information
RFID can expand loss prevention from pure alerting to data-based control.
RFID as EAS: Article surveillance with article data
RFID as EAS combines protection logic with item visibility and can make article surveillance more data-based.
RFID and self-checkout: combining convenience and control
Self-checkout needs processes that bring together customer speed and security logic.
Select RFID labels: Buy directly or test first?
Not every RFID label fits every product. The selection should take into account application, material and process.
Plan an RFID pilot: From the test store to reliable results
A good RFID pilot not only demonstrates technology, but also measurable process benefits.
RFID business case: Which costs and benefits count?
RFID pays off not only through faster inventory, but also through better visibility and operational impact.
RFID and data protection: What retailers should consider
RFID can enable powerful processes. In the customer context, however, transparency and data protection awareness are needed.
RFID in Fashion: Why sizes, colors and variants have to be visible
Fashion is one of the strongest RFID use cases because variants directly determine sales.
RFID in drugstores, beauty and cosmetics
Drugstore and beauty are demanding: small products, liquids, metallization, value density and loss prevention.
RFID for food, freshness and reusable packaging
Food RFID is demanding, but particularly interesting for reusability, traceability and process visibility.
Next step
Don’t just read RFID, but start it correctly.
If a topic fits your project, we will examine the use case, product, material, inlay, hardware, coding and pilot logic together.
