Our RFID trailer seal tag combines long-range UHF identification, a galvanized steel cable and electronic status detection in an IP66 ABS housing. It is designed for controlled trailer routes where dispatch teams need to identify the assigned seal and retrieve its available status data before opening.
Long-Range RFID Trailer Seal Specifications
The battery-assisted configuration provides more memory and a longer reading zone than a compact passive trailer tag, while final performance still depends on the reader, placement and operating environment.

| EPC memory | 192 bits | Allocate the seal, trip or shipment identity. |
| User memory | 512-bit User File_0 | Approve the data map before encoding. |
| Reserved memory | 112 bits | Define password and access ownership. |
| Operating frequency | 865–868 MHz | Confirm ETSI-region deployment. |
| Reference read range | Up to 25 m, reader dependent | Test the complete gate or yard installation. |
| Housing and cable | ABS housing and galvanized steel cable | Verify the closure geometry and cable route. |
| Wire diameter | 4 mm, customizable | Provide the required diameter and length. |
| Protection | IP66; on-metal use supported | Validate the applied transport environment. |
| Sensors | Detection and temperature sensors | Define the required data and alert rules. |
| Battery | Embedded 165 mAh coin cell | Confirm storage, activation and trip duration. |
Use the Seal as a Controlled Trip Device
Each electronic seal should move through a defined lifecycle so its RFID identity, physical installation and detected status remain connected to the same trailer movement.
Commission
Register the EPC, TID, visible serial number, encoding result and initial device record.
Lock
Install the cable on the approved trailer closure and assign the seal to the active trip.
Interrogate
Read the seal at authorized gates or inspection points and store the returned event data.
Close
Reconcile the arrival result, opening authorization and final device disposition.
Define What Each Trailer Status Means
Software should interpret the available seal state within the trip workflow instead of treating every RFID response as proof that the load is secure.
| Operational Condition | System Comparison | Required Action | Record Outcome |
|---|---|---|---|
| Prepared for dispatch | Seal identity matches the assigned trip | Confirm installation and departure approval | Open an active seal-use record |
| Expected locked result | Returned status agrees with the trip stage | Allow the configured checkpoint process | Store time, reader and facility |
| Unexpected status | Seal result conflicts with the expected stage | Hold the trailer for controlled inspection | Create an exception event |
| Unknown identity | EPC is absent from the active trip records | Do not approve the vehicle automatically | Route the scan for investigation |
| Authorized opening | Receiver and trip are approved for closure | Record the opening under the receiving procedure | Close the active seal record |
Plan Long-Range Reads Without Cross-Lane Errors
Gate Identification
Position antennas to cover the intended trailer lane while limiting unintended reads from queued vehicles and stored seals.
Yard Verification
Use controlled handheld or vehicle-side reading procedures when trailers are parked close together.
Receiving Control
Retrieve the expected trip first, then compare the received identity and available status before opening.
Use Temperature Data Within Defined Limits
The listed temperature sensor can contribute data to a transport record, but the buyer must define how readings are obtained, interpreted and compared with shipment requirements.
Reader Interaction
- Supported sensor-reading command
- Reader firmware compatibility
- Permitted interrogation distance
- Required retry procedure
Data Interpretation
- Temperature unit and data format
- Reading time and checkpoint
- Accepted operating thresholds
- Exception-review responsibility
Shipment Record
- Seal-to-trip relationship
- Reader and facility identity
- Recorded sensor value
- Inspection or release decision
Allocate the Available RFID Memory
| Memory Area | Available Size | Suitable Use | Data Management Requirement |
|---|---|---|---|
| TID/UID | 112 bits | Device identity during commissioning | Store its relationship with the supplied seal |
| EPC | 192 bits | Primary RFID seal or trip identifier | Use a controlled unique-number structure |
| User File_0 | 512 bits | Approved operational data fields | Document offsets, encoding and update rights |
| Reserved | 112 bits | Security and device-control functions | Restrict password ownership and distribution |
| Backend record | Defined by buyer's system | Route, cargo, driver and event history | Keep detailed changing data off the tag |
Validate the Installed Electronic Seal
Fit Test
Confirm the cable diameter, length, bend radius and housing clearance on the trailer.
Range Test
Measure reliable reads across the real lane, antenna positions and trailer orientations.
State Test
Exercise the approved operating sequence and confirm the returned data at each stage.
Exception Test
Present an unknown identity, wrong trip and unexpected state to the software workflow.

RFID Trailer Seal Tag Questions
How does this model differ from a passive trailer tag? +
This model combines a battery-assisted long-range configuration, larger memory, electronic status detection and a temperature sensor. It requires additional reader, software, activation and battery-life planning.
Is the 25-metre reading distance guaranteed? +
No. It is a reference maximum dependent on the reader, antenna, permitted power, tag orientation, installation position, metal structures, vehicle spacing and local interference.
Does the temperature sensor replace a validated logger? +
Not automatically. Confirm the measurement range, accuracy, sampling behavior, data retrieval method and validation requirements before using the sensor for a regulated or contractual temperature record.
Does the seal continuously transmit trailer location? +
No GPS or cellular location function is established by the listed specification. Visibility is created when compatible readers interrogate the seal and software associates those reads with known locations.
How should the stated battery life be evaluated? +
The page lists up to 12 months after locking. Actual service duration should be evaluated against storage time, activation point, interrogation frequency, temperature and the complete configured operating mode.
Can the tag operate directly beside trailer metal? +
The listed configuration supports on-metal use, but the final housing position, antenna orientation, clearance and reading zone must still be tested on the intended trailer construction.
What information is required for configuration review? +
Please provide the trailer closure, cable dimensions, trip duration, operating region, reader setup, required states, temperature workflow, memory map, artwork, encoding data and quantity.
Define the Electronic Seal and Trip Workflow
Send us the trailer closure, cable dimensions, operating region, reader layout, state workflow, temperature requirements, memory map, artwork, encoding data and quantity for review and pricing.
