The tag supplies a credential identifier. Payment status belongs to the configured payment and access workflow, where that association is included. Define how the identifier is linked to the relevant permit, account or transaction and test the intended access result. Possessing or successfully reading a tag does not itself establish a paid parking entitlement.
Credentials and identification
UHF vehicle access tag
The UHF tag provides an identifier for vehicle access. It works with the lane’s UHF reader and the permissions associated with that credential.
- Role
- Vehicle tag credential
- Interaction
- Read in a defined lane zone
- Compatibility
- Product-specific compatibility
Credential system
Match the vehicle tag to the reader and its read zone.
A UHF tag is the credential that accompanies the vehicle. Its reference, placement and registration determine how it is used by the installed reader and access system.
Will any UHF tag work with the reader?
No. Confirm the supported tag technology and encoding for the installed reader. Validate the chosen tag with the actual vehicle and lane before issuing a larger batch; the UHF label alone does not establish compatibility.
Where should the tag be placed?
Use the placement specified for the selected tag and vehicle. Test that position along the normal approach, including neighboring vehicles and lanes. Do not assume that the same placement works for every vehicle or that maximum read range defines the best read zone.
Can a tag be moved to another vehicle?
Check the tag’s mounting and reuse instructions before moving it. Update the vehicle assignment and access rights, remove any obsolete credential, and test the replacement position. A physical transfer alone does not update the access record.
Vehicle credential placement
Place the tag where the reader can use it.
A UHF tag becomes useful at the entrance when its technology, mounting and assigned access record work together.
- Match the reader
- Use the tag technology supported by the installed reader.
- Assign the vehicle
- Register the credential against the intended vehicle or access record.
- Check the approach
- Test reading with the tag installed on the actual vehicle in the intended lane.
Technical Characteristics
| Specification | Details |
|---|---|
| Frequency | UHF RFID; regional band matched to the selected tag and reader |
| Read Range | Depends on tag, reader, antenna and installation; confirmed for the selected configuration |
The tag format and physical specifications are confirmed with the selected UHF model.
Equipment details
The tag assigned to the vehicle
The UHF tag provides an identifier for vehicle access. It works with the lane’s UHF reader and the permissions associated with that credential.
| Component or use | How it fits the system |
|---|---|
| On the vehicle | The tag is positioned on the vehicle for the chosen reader arrangement. Its placement is tested from the normal approach to the entrance. |
| Matching reader | A UHF reader captures the tag identifier in its read zone. Reader, tag reference and placement work together. |
| Vehicle credential | The identifier is enrolled in the access system and assigned the permissions needed for the relevant lane or site. |
| Vehicle changes | When a vehicle or tag changes, update the credential assignment and remove obsolete access. Recheck placement for the replacement. |
Configuration: Chip, frequency, memory, encoding, read range, material, printing, environmental behavior and compatibility depend on the selected product reference.
Equipment questions
Practical details for planning, operating and maintaining this equipment.
Decide whether permission follows the vehicle credential, a named person or another supported arrangement, and document who may use it. Keep the assignment and exception process consistent with that policy. A vehicle tag read does not by itself identify the person driving, so any requirement to verify the driver needs a separate approved process.
