Raylink RFID tag family overview — labels, inlays, anti-metal, laundry and tamper-evident tags

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.

  • 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

Raylink tamper-evident UHF RFID labels with peeled antenna layer

Removal and seal-state indication

UHF RFID Chip Parameters

Use the chip table as an initial memory and sensitivity reference. Final tag performance still depends on the antenna design, tag construction, object, mounting and reader environment.

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.

01

Tagged object

Confirm the object material, size, curvature, contents, movement and whether the tag will be hidden, stacked or handled.

02

Read zone

Define the required distance, orientation, reader antenna, tag population and unwanted-read boundary.

03

Environment

Review metal, liquid, temperature, moisture, UV, chemicals, wash cycles, impact and outdoor exposure.

04

Construction

Select the label, inlay, spacer, housing, adhesive, attachment and converting format required by the project.

05

Chip and memory

Confirm protocol, sensitivity, EPC length, User memory, TID, Access/Kill requirements and any sensor or security function.

06

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.
