ANPR Cameras Read Registered Vehicle Plates for Toll Payments via JustGO

Automatic Number Plate Recognition (ANPR) cameras facilitate toll payments by reading registered vehicle plate numbers, enabling seamless passage through toll plazas. Users of the JustGO application simply need to download the app, register their vehicle and account, and link a payment card. Subsequently, ANPR cameras capture images of the vehicle's license plate, cross-reference it with the registered information within the JustGO system, and process the toll deduction from the linked payment card. This system allows registered users to utilise any available lane, eliminating the need for specific lanes designated for different payment methods.
ANPR System Functionality for Toll Collection

The ANPR system's core function involves high-speed cameras strategically positioned at toll plazas to capture images of approaching vehicles. These cameras are equipped with optical character recognition (OCR) technology, which is a type of artificial intelligence that can identify and extract text from images. In the context of toll collection, the OCR software identifies the alphanumeric characters on a vehicle's license plate. This extracted plate number is then digitally processed and matched against a database of registered vehicles, such as those linked to the JustGO application for open toll payment systems.
Integration with JustGO Application and Payment Processing

For the open toll payment system implemented by PLUS Malaysia Berhad, the ANPR cameras are integrated with the JustGO application. When a vehicle passes through a toll plaza equipped with ANPR, the cameras read the license plate. This data is transmitted to the JustGO system, which verifies the plate number against its user database. If a match is found, the system identifies the associated payment card and initiates the toll deduction. This process allows for a contactless and efficient payment method, as users do not need to stop or present a physical toll card.
Expansion of ANPR Technology in Malaysian Highways

PLUS Malaysia Berhad has been progressively expanding the deployment of ANPR technology for its open toll payment system. This initiative, which began with a public pilot project in January 2026 across nine toll plazas on the North-South Expressway (NSE), has seen further implementation. Most recently, six additional toll plazas in the Southern Region, including those on the Seremban-Port Dickson Expressway, the North-South Expressway, and the Malaysia-Singapore Second Link Expressway, have been incorporated into this system. This expansion aims to bring the ANPR-based open toll payment system to a wider network of highways in Malaysia.
