When you’re mounting RFID tags on metal surfaces or metal products, you should be aware that if you use non metal mount RFID tags, your system will not function as desired as the metal will detune any passive RFID tag that is not designed to be placed on metal. Using tags that are specifically calibrated to the materials you need to track makes reading, tracking, and inventorying them easier and provides for greater read range.
Metal mount RFID tags are typically rugged, difficult to damage, and easy to weld, screw or otherwise attach.

Why Use an Anti-Metal RFID Tag?

Metal can significantly affect the performance of conventional passive RFID tags. When a standard RFID tag is attached directly to a metal surface, the metal can interfere with the tag antenna and change its electrical characteristics. This may result in shorter read distances, unstable communication, or failure to read the tag.

An on-metal RFID tag is designed specifically for this type of application. Its structure separates and protects the RFID antenna from the conductive metal surface, helping the tag maintain more stable RFID performance.

For example, a warehouse may need to identify metal shelving, server cabinets, electrical equipment, tools, or industrial machinery. Instead of trying to place a conventional label on a non-metal area, an anti-metal RFID tag can be mounted directly onto the asset.

This makes the identification process more flexible and can simplify asset registration, inventory, and tracking.

Anti-Metal RFID Tag vs. Standard RFID Tag

Choosing the correct RFID tag is particularly important when the tracked asset contains metal.

A standard RFID label may be suitable for cardboard boxes, plastic containers, and other non-metal products. For metal assets, however, an anti-metal RFID tag is generally the more appropriate choice.

How Does an On-Metal RFID Tag Work?

An anti-metal RFID tag uses a specially designed RFID antenna structure and a ferrite layer between the antenna and the metal surface.

When the tag is installed on a metal object, the ferrite material helps isolate the RFID antenna from the conductive surface. This allows the antenna to operate more effectively than a conventional RFID inlay directly attached to metal.

The basic RFID process remains the same:

1. The RFID reader sends a UHF radio signal.
2. The passive RFID tag receives energy from the reader.
3. The RFID chip processes the reader’s command.
4. The tag sends its stored identification data back to the reader.
5. The RFID software associates the tag ID with the corresponding asset or inventory record.

This enables automated identification without requiring direct line-of-sight scanning.

RFID Warehouse Management Applications

The UHF anti-metal RFID tag is well suited to warehouse environments where many assets need to be identified quickly and repeatedly.

Metal shelving, pallets, containers, machinery, tools, and storage equipment can all create challenges for conventional RFID labels. An anti-metal tag provides a practical option for identifying these assets.

Common warehouse applications

By linking each RFID tag’s unique identifier with warehouse software, companies can create a digital record for each physical asset.

IT Asset Management

One of the key applications for this RFID tag is IT asset management.

Servers, computer hosts, network switches, server chassis, racks, and other IT infrastructure commonly contain significant amounts of metal. These assets can be difficult to label with standard RFID tags.

An anti-metal RFID tag can be mounted on suitable metal surfaces and associated with an asset record in an IT asset management system.

A typical workflow may include:

• Assigning an RFID tag to an IT asset
• Recording the RFID ID in the asset database
• Installing the tag on the equipment
• Scanning assets during inventory checks
• Recording asset location and movement
• Supporting periodic audits
• Updating maintenance or service records

This can reduce the amount of manual barcode scanning required during large-scale inventory operations.

Logistics and Supply Chain Tracking

RFID is widely used to improve visibility throughout logistics operations. However, many reusable transport assets are made from or contain metal.

Examples include metal containers, equipment cases, transport racks, cages, carts, and logistics equipment.

An anti-metal RFID tag can provide a durable identification method for these reusable assets.

When RFID readers are installed at warehouse entrances, exits, workstations, or inspection points, tagged assets can be identified automatically as they pass through the reading area.

Mounting Options

The RFID tag supports multiple installation methods, helping users select the most suitable mounting solution for different assets.

Screw mounting

Screw mounting provides a mechanical attachment method for assets where a permanent and secure installation is required. It can be particularly useful for equipment, machinery, racks, and other durable assets.

3M adhesive mounting

A 3M adhesive layer can provide a faster installation method when drilling or modifying the asset is undesirable.

Before applying adhesive, the mounting surface should be clean, dry, and free of oil or dust. For outdoor or demanding applications, the selected adhesive should also be evaluated against temperature, humidity, vibration, and surface conditions.

IP67 Protection for Demanding Environments

The tag has an IP67 protection rating, making it suitable for applications where protection against dust and temporary water immersion is required under the applicable IP testing conditions.

This makes the tag more suitable for demanding environments than an exposed paper RFID label.

However, IP protection does not mean that every installation environment will have identical RFID performance. Extreme temperatures, metal structures, liquids, other RF sources, and tag orientation can all influence actual RFID read performance.

For this reason, application-specific testing is recommended for large deployments.

Available RFID Chips

The tag can be configured with different RFID chips depending on project requirements.

Chip selection can depend on memory requirements, reader compatibility, application software, supply requirements, and project specifications.

If a particular RFID chip is required by an existing RFID system, customers can confirm the chip model before production.

RFID Frequency and Compatibility

This anti-metal RFID tag operates across the 860–960 MHz UHF RFID frequency range and uses the ISO 18000-6C protocol.

UHF RFID is commonly selected for warehouse and asset management because it can identify multiple tags without requiring the reader to physically contact each asset.

The actual operating frequency may be configured according to the target market and applicable regional RFID regulations.

Before deployment, the complete RFID system should be evaluated, including:

• RFID reader
• Reader antenna
• Tag orientation
• Mounting surface
• Reader output power
• Software
• Environmental conditions
• Required read zone

The tag should therefore be evaluated as part of the complete RFID system rather than as an isolated component.

RFID Tag Selection Guide

Different assets require different RFID tag designs. The following guide can help determine whether an anti-metal tag is appropriate.

If the asset is primarily non-metallic, a conventional UHF RFID label may be more economical. If the tag must be attached directly to metal, an anti-metal design should generally be considered.

Benefits for RFID Warehouse Management Systems

An RFID warehouse management system can use RFID tag IDs to associate physical assets with digital records.

Compared with manual identification processes, RFID can support faster inventory operations and more automated asset identification.

Typical system architecture includes:

RFID Tag → RFID Reader → RFID Antenna → RFID Middleware → Warehouse Management Software

The RFID tag stores the unique identification information. Readers capture the tag data, while middleware and warehouse software process the information and connect it to inventory records.

For example, when a tagged asset enters a designated RFID reading zone, the system can record the asset ID and update its movement or inventory status.
