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.
Short description: Not every product is equally easy to tag. Material and packaging are crucial to RFID success.
RFID works via radio. Therefore, product materials and packaging influence performance. Metal, liquids, metallized foils and tight packaging can make RFID readings particularly difficult.
This is important for retail projects because many product ranges do not consist of ideal test items.
Briefly explained
Metal can reflect signals and upset standard tags. Liquids can attenuate or absorb UHF energy. Packaging made of film, glass, plastic or composite materials also changes behavior.
The answer is not to exclude such products altogether. Rather, it requires suitable inlays, positioning, tests and sometimes special labels.
Why this is relevant for traders
Drugstores, beauty, food, electronics and DIY are typical areas where material issues become important. Small, valuable or difficult to package items in particular require careful selection.
Anyone who ignores material influences risks poor read rates and declining trust in RFID data.
Practical example
A perfume box with a metallized surface and a glass bottle can show different RFID behavior than a textile hangtag. A standard label that works for Apparel is not automatically suitable.
What you should pay attention to
- Analyze product material early.
- Test packaging and contents.
- Check special inlays for metal or liquid.
- Include realistic box and store scenarios.
Common mistakes
- Just decide based on label size.
- Skip material testing.
- Transferring a successful apparel label to other product groups.
- Enforcing incorrect positioning through packaging design.
Practice checklist
- Is there metal or liquid?
- Is the packaging metallized?
- How tightly are products stored?
- Which label position is possible?
- What tests are required?
FAQ
Can RFID work on metal?
Yes, but often it requires specifically suitable tags or positioning.
Are liquids problematic?
They can attenuate UHF RFID and should be tested.
Is packaging important?
Yes. Packaging affects readability, positioning and source tagging.
