How RFID and ANPR Work Together in an Unmanned Weighbridge System

in

Why Use RFID and ANPR Together?

RFID and ANPR are both used for vehicle identification, but they work in different ways. RFID identifies a vehicle using a tag or card. ANPR identifies a vehicle by reading the number plate.

When both technologies are used together, the system becomes more secure and reliable.

Truck Scale Automation

RFID Strength

RFID is fast and consistent. It is suitable for regular fleets, repeated vehicles, and controlled truck movements. Once a tag is assigned to a vehicle, the system can quickly retrieve the vehicle details.

ANPR Strength

ANPR provides visible verification of the vehicle number plate. This is important when outside vehicles visit the site or when the company wants image proof of the transaction.

Combined Workflow

A truck arrives at the gate. The RFID reader detects the tag. At the same time, the ANPR camera captures the number plate. The software compares both records.

If the RFID tag and number plate match the registered vehicle, the system allows the vehicle to proceed. If there is a mismatch, the system can alert the operator or block the transaction.

Fraud Prevention

Using both RFID and ANPR helps prevent tag swapping and wrong vehicle entry. It also creates a stronger audit trail because the transaction includes both digital tag identity and number plate image evidence.
