RFID tag families
Choose the tag construction before the chip
Start with the tagged object, mounting surface, environment and required read zone. Then confirm the inlay, chip memory, adhesive, housing and production format as one tag configuration.
Product lineup
UHF RFID Tag Families
Compare the tag construction first, then confirm the mounting surface, temperature, chemicals, wash process, tamper behavior, sensor requirement, chip memory and final converting format.
Printable and converting materials
RFID Labels and Inlays
Printable adhesive RFID media
UHF RFID Labels
Printable UHF RFID labels combine a face material, adhesive, inlay and liner for cartons, packaging, documents and general asset identification.
- Confirm face stock, adhesive and final mounting surface
- Match label size, inlay position and printer encoding zone
- Validate barcode, print durability and RFID performance together
Dry and wet inlay components
UHF RFID Inlays
UHF RFID inlays provide the antenna and chip structure used by converters and equipment builders to create application-specific labels and embedded tag constructions.
- Select antenna size and chip according to the read zone
- Confirm dry or wet construction, pitch and web direction
- Validate converting, lamination and final material interaction
Printable labels for medical identification
Medical UHF RFID Labels
Medical UHF RFID labels provide item-level identification for medical consumables, records, specimen containers and smart-cabinet inventory, combining a printable face stock, adhesive and a UHF inlay tuned for medical packaging.
- Confirm the labeled item, surface material and curvature
- Review read performance inside cabinets, on shelves and in stacked storage
- Validate printing, encoding, adhesive and any tamper or archiving requirement
Industrial and material-specific tags
Tags Designed Around the Object and Environment
Metal-mounted RFID construction
Flexible UHF Anti-Metal RFID Tags
Flexible UHF anti-metal RFID tags use a low-profile tuned layer or spacer to maintain performance when adhered directly to metal tools, equipment enclosures and reusable assets.
- Confirm metal type, available footprint and surface curvature
- Review read distance, orientation and nearby metal geometry
- Validate adhesive, print surface, flexing and environmental exposure
Durable reusable asset tags
Rigid UHF RFID Tags
Rigid UHF RFID tags use a protective housing for returnable assets, containers, tools, vehicles and industrial equipment exposed to handling or impact.
- Select enclosure, mounting holes and attachment method
- Confirm IP, impact, UV and chemical requirements
- Validate the tag on the actual asset and installation angle
Strap-mounted reusable identification
UHF RFID Cable-Tie Tags
UHF RFID cable-tie tags combine a UHF inlay with a locking nylon strap for assets that have no flat adhesive surface, such as pallets, cages, cables, hoses, gas cylinders and outdoor equipment.
- Confirm strap length, locking style and tag position on the object
- Review read range, orientation and nearby metal or liquid
- Validate strap strength, outdoor exposure and one-time or reusable locking
Washable textile identification
UHF Laundry RFID Tags
Laundry RFID tags are designed for repeated textile identification through washing, drying, pressing and garment circulation workflows.
- Confirm wash cycles, peak temperature and chemical exposure
- Choose sew-in, heat-seal, pouch or button construction
- Test folding, stacking and reader placement in the real process
Liquid-container RFID tuning
On-Liquid UHF RFID Tags
On-liquid UHF RFID tags use a construction and antenna position selected for bottles, containers and products whose liquid content changes RF behavior.
- Confirm container material, liquid type and fill level
- Review label position, orientation and curvature
- Validate the full and empty container states where relevant
Process-resistant RFID identification
High-Temperature Resistant UHF Tags
High-temperature UHF RFID tags are selected for industrial processes where the tag must tolerate defined heat exposure while remaining readable afterward.
- Confirm continuous and peak temperature separately
- Review exposure duration, pressure, chemicals and cooling cycle
- Validate mounting and post-process read performance
Control and sensing tags
Tamper and Condition-Monitoring RFID Tags
Removal and seal-state indication
Tamper-Evident UHF Tags
Tamper-evident UHF RFID tags are designed to change, break or transfer when removed so the physical seal state can support product and asset control.
- Define the required break, transfer or destruct behavior
- Confirm substrate adhesion and removal direction
- Validate what the reader or software should detect after tampering
Passive condition-monitoring tags
Temperature-Sensing UHF Tags
Temperature-sensing UHF RFID tags combine identification with sensor data for projects that need item-level temperature records or threshold checks.
- Confirm sensing range, accuracy and logging method
- Review reader, command and software compatibility
- Validate sensor placement, response time and data interpretation

Selection logic
What to Confirm Before Choosing an RFID Tag
Treat the tagged object, read zone, environment, construction, chip and production process as one tag configuration.
Tagged object
Confirm the object material, size, curvature, contents, movement and whether the tag will be hidden, stacked or handled.
Read zone
Define the required distance, orientation, reader antenna, tag population and unwanted-read boundary.
Environment
Review metal, liquid, temperature, moisture, UV, chemicals, wash cycles, impact and outdoor exposure.
Construction
Select the label, inlay, spacer, housing, adhesive, attachment and converting format required by the project.
Chip and memory
Confirm protocol, sensitivity, EPC length, User memory, TID, Access/Kill requirements and any sensor or security function.
Sample validation
Test the production tag, reader, object, mounting, movement, environment, encoding and software workflow together.
RFID tag workflows
Match the Tag to the Object, Environment and Read Point
A tag family becomes useful only after its construction, chip and mounting method are validated in the actual operating workflow.
Retail, logistics and document labels
Use printable labels or converted inlays for item, carton, shipment, document and general asset identification.
Industrial assets and reusable equipment
Use anti-metal, rigid or process-resistant tags for tools, machinery, containers, vehicles and work-in-process assets.
Textile, liquid and condition monitoring
Use laundry, liquid-compatible, tamper-evident or sensing constructions when the environment changes standard label behavior.
FAQ
RFID Tag Questions
How do I choose the correct UHF RFID tag?
Start with the tagged object, mounting surface, operating environment and required read zone. Then choose the tag construction, antenna, chip memory and attachment method and validate samples on the real item.
Does higher chip sensitivity always create a longer read range?
No. Chip sensitivity is one input. Antenna design, tag size, object material, orientation, reader output, reader antenna and the RF environment all affect the final read range.
Which RFID tags work on metal?
Use a tag specifically designed for metal, such as an anti-metal label, spacer construction or rigid on-metal tag. A standard paper label normally requires separation from the metal surface.
Can a standard UHF RFID label be placed on a liquid container?
Liquid can detune a standard inlay. Select a liquid-compatible construction and validate the container material, liquid type, fill level, label position and orientation.
How should I choose the chip and memory size?
Confirm the EPC structure, User memory, TID requirement, Access/Kill use, security or sensor functions, encoding equipment and software data model before selecting the chip.
What information should I send for tag sample matching?
Send the object material and dimensions, photos, mounting position, required distance, reader and antenna, environment, label size, printing/encoding process and estimated quantity.
