Industrial RFID Tags for Metal Surfaces

RFID tags for metal surfaces are used for the identification and tracking of industrial equipment, fixed assets, tools, metal containers, components and other objects where conventional RFID labels may not perform reliably.

Metal can significantly affect the performance of standard RFID antennas. For this reason, special on-metal RFID tags are designed to operate directly on metallic surfaces while maintaining stable read performance.

RFID identification can be used not only to assign a unique ID to an asset, but also to support automated inventory, movement control, maintenance processes, traceability and digital asset records.

Where On-Metal RFID Tags Are Used

• industrial equipment identification;
• fixed asset inventory and tracking;
• tool and fixture management;
• metal container and reusable asset identification;
• component and assembly identification;
• equipment and spare part traceability;
• maintenance and repair asset tracking;
• RFID inventory in production and warehouse environments.

Why Standard RFID Labels Perform Poorly on Metal

Metal changes the electromagnetic environment around an RFID antenna and may significantly reduce the read range or make standard RFID labels unstable or unreadable.

On-metal RFID tags use a specialized antenna structure and construction designed specifically for installation on metallic surfaces. Correct tag selection and placement are essential for reliable performance.

RFID Identification of Equipment and Fixed Assets

One of the most common applications for on-metal RFID tags is equipment and asset identification. Each physical asset can receive a unique RFID tag linked to a record in an ERP, EAM, CMMS or asset management system.

The digital asset record can include:

• equipment name and category;
• serial number and asset ID;
• current location;
• responsible department or employee;
• movement history;
• technical condition;
• maintenance and repair records;
• inventory verification results.

RFID + Barcode + Data Matrix

Industrial RFID tags can combine several identification technologies on one physical label.

Depending on the tag design, the printable surface can include:

• asset or inventory number;
• serial number;
• Code 128 barcode;
• Data Matrix code;
• QR code;
• text and operational information;
• company logo.

This allows the same object to be identified by RFID, barcode, 2D code or visually by a human-readable number.

Types of RFID Tags for Metal Surfaces

Different applications require different on-metal RFID tag designs. Tags may vary in size, read range, RFID chip, memory capacity, durability and printing options.

Available solutions include:

• identytag OnMetal Global Label 54 x 25 mm — a compact and versatile RFID tag for equipment, containers and other metal assets;
• identytag OnMetal Global Label Mini 54 x 13 mm — a narrow compact RFID tag for objects with limited space available for labeling;
• inotec Flex On Metal Global — a larger industrial RFID label for durable identification and customized printing.

How to Select the Right RFID Tag

The correct RFID tag depends on more than just its size or chip type. Important factors include the material and geometry of the object, available mounting area, tag position, required read range, operating environment, antenna orientation and requirements for printed information.

Compact tags such as 54 x 13 mm models are useful where labeling space is limited. Larger tags may provide more room for printed information and can offer better read performance in certain applications.

Automated RFID Inventory

RFID technology can significantly improve inventory processes for equipment and other physical assets.

Unlike barcodes, RFID does not require precise line-of-sight scanning of every individual tag. Depending on the system design, tagged objects can be detected at a distance using mobile or fixed RFID readers.

Typical RFID inventory solutions may include:

• handheld RFID terminals;
• mobile RFID readers;
• fixed RFID readers;
• RFID gates and portals;
• integrated RFID systems for movement control.

Industrial RFID Tags from identytag and inotec

RFID tags from identytag and inotec are designed for industrial, logistics, maintenance, warehouse and asset management applications.

Depending on the model, different RFID chips, memory configurations, printing options and pre-encoding services are available.

RFID Tag Selection and Testing

Before full-scale deployment, RFID tags should be tested on the customer's actual assets and in the real operating environment.

Typical testing includes:

• tag placement and mounting position;
• read stability;
• actual read range;
• orientation relative to the RFID antenna;
• barcode and Data Matrix print quality;
• ease of use for personnel;
• compatibility with RFID readers and software systems.
