Key Features of UHF EPC Gen2 RFID Vehicle Tag
This passive RFID glass tag is designed for applications where reliable identification, long service life, and low maintenance are required.
Long-Range Identification
Operating in the UHF frequency range of 860–960 MHz, the tag enables longer reading distances compared with traditional low-frequency RFID solutions. When combined with a suitable UHF RFID reader and antenna, it can support vehicle recognition from several meters away.
Battery-Free Operation
The tag uses passive RFID technology and does not require an internal battery. This provides:
- Extended service life
- Lower maintenance costs
- Smaller product size
- Better reliability for long-term vehicle applications
Durable Glass Encapsulation
The glass tube housing protects the internal RFID chip and antenna from moisture, dust, vibration, and environmental changes.
The sealed structure makes it suitable for:
- Outdoor vehicle identification
- Parking systems
- Industrial asset tracking
- Fleet management
EPC Gen2 Standard Compatibility
The RFID tag follows the EPC Class 1 Gen2 standard, allowing compatibility with many global UHF RFID readers and systems.
How Does a Passive UHF RFID Glass Tag Work?
A passive UHF RFID vehicle tag works through wireless communication between the RFID reader and the embedded RFID chip.
The identification process includes three main steps:
1. RFID Reader Sends Radio Signal
The UHF RFID reader continuously sends electromagnetic waves through its antenna.
2. Tag Receives Energy
The RFID antenna inside the glass tag captures the radio frequency energy and activates the RFID chip.
3. Data Transmission
The chip responds by sending stored EPC identification information back to the reader.
The complete process happens within milliseconds, allowing vehicles to be identified quickly without manual scanning.
Passive RFID Glass Tag vs Other Identification Technologies
Different vehicle identification technologies have different advantages. The following comparison shows why UHF RFID is widely used for automatic vehicle management.
| Technology | Reading Distance | Battery Required | Advantages | Limitations |
|---|---|---|---|---|
| Passive UHF RFID Tag | Several meters | No | Low cost, long lifespan, automatic identification | Requires RFID reader |
| Active RFID Tag | Dozens to hundreds of meters | Yes | Longer range and real-time tracking | Higher cost and maintenance |
| NFC Tag | Few centimeters | No | Easy smartphone interaction | Very short reading distance |
| Barcode Label | Short distance | No | Very low cost | Requires visual scanning |
For vehicle identification applications, passive UHF RFID provides a balanced solution between performance, cost, and reliability.
Main Applications of Vehicle RFID Glass Tags
Smart Parking Management
UHF RFID vehicle tags are widely used in automatic parking systems.
When a vehicle approaches an entrance or exit, the RFID reader detects the tag ID and communicates with the parking management system.
Typical functions include:
