For more than a century, the paper tax disc has been a familiar fixture of Irish motoring. Introduced in 1921, it began life as a simple proof-of-payment receipt for motor tax and has since become a visible symbol of compliance on Irish roads.
That era is now coming to an end.
Under the National Vehicle and Driver File Bill 2025, Ireland plans to abolish the paper tax disc, replacing it with a fully digital verification model supported by Automatic Number Plate Recognition (ANPR). The Department of Transport estimates savings of €5.8 million through reduced printing and distribution costs.While the financial rationale is clear, experience elsewhere suggests the transition may carry hidden risks.
The UK precedent - and its unintended consequences
Ireland is not the first country to take this step. The UK removed its tax disc system over a decade ago, shifting entirely to digital enforcement. However, concerns have since escalated there to the point where a public inquiry has been launched, following warnings from MPs, industry experts and law enforcement agencies about widespread abuse of vehicle registration plates.
Central to the problem is the emergence of illegal and undetectable number plates - commonly known as ‘ghost’ or stealth plates. These plates appear compliant to the naked eye but are deliberately engineered to evade ANPR systems using transparent films, raised or distorted characters, and subtle alterations that defeat camera recognition.A major new report from the All-Party Parliamentary Group for Transport Safety (APPGTS) warns that the UK’s outdated and weakly regulated number plate regime has enabled a rapidly growing crisis. The report concludes that criminals and organised crime groups are exploiting systemic vulnerabilities to operate undetected on the road network, avoid enforcement, and drain public revenues.
ANPR under strain
The findings are particularly striking given the scale of the UK’s ANPR infrastructure. The system now processes approximately 90 million vehicle reads per day across more than 18,000 cameras. Yet the inquiry found that weak regulation of plate production, unregulated online supply chains, and insufficient enforcement are critically undermining its effectiveness.
As many as one in fifteen vehicles on UK roads may now be using modified or non-compliant plates. These are routinely used to avoid tolls, congestion charges, road pricing schemes and fines. More concerning still, ANPR-evasive plates have been linked to serious criminal activity, including drug trafficking, rogue trading, human trafficking and people smuggling.
A national security issue
Evidence submitted to the inquiry by National Trading Standards raised serious national security concerns. Ghost plates, it warned, allow vehicles to bypass surveillance systems around airports, government buildings and major transport hubs, creating vulnerabilities that could be exploited for vehicle-borne attacks.Professor Fraser Sampson, a Professor of Governance and Data Protection at Cranfield University who leads the Vehicle Identification Group, recently highlighted a fundamental weakness in the UK current approach: “For all its technological advancement and operational indispensability, the ANPR system still relies ultimately on a piece of plastic affixed to either end of a vehicle.”
Served by what he described as a “wholly unregulated market,” the number plate has become a single, readily exploitable point of failure - one that can be defeated with little more than cellophane, foliage or a marker pen. This would equally apply to Ireland.
Public safety and revenue at risk
Beyond national security, the report identifies acute public safety risks. Evidence suggests widespread tampering by taxi drivers to avoid drop-off and road charges, creating traceability gaps that disproportionately affect women, girls and vulnerable passengers. When vehicles become effectively untraceable, accountability is lost.The APPGTS report concludes that the UK’s registration plate system represents a “gaping hole” in policing and enforcement infrastructure.
What this means for Ireland
As Ireland prepares to remove the paper tax disc, a critical question emerges: is the country adequately prepared for the enforcement and security challenges that may follow? Certainly, UK experts in the field urge caution and highlight the increased fraud, enforcement difficulties, lost revenue and heightened risk to motorists following the removal of physical tax discs - despite the UK having a far denser ANPR camera network than Ireland.
Angus Hone from the Cranfield University Vehicle Identity Group, recently commented on LinkedIn: “If Ireland follows the UK pattern, the savings from removing the paper tax disc may be dwarfed by revenue losses. Declared vehicle excise duty losses in the UK are significant, and our research indicates the true figures are far higher. Vehicle identification is more complex than ‘just the humble number plate’ and demands a more sophisticated response. We strongly recommend delaying the removal of the paper disc until a robust and secure alternative is fully in place.”
Insurance Issues to consider
In addition, a recent report from the Motor Insurers' Bureau of Ireland (MIBI) has shown that a shocking total of 19,673 vehicles were seized by gardaí last year for being driven without insurance. In addition to the vehicles seized, a further 51,024 charges and summons have been issued to those apprehended for driving without insurance since 2024, with 25,009 of those charges and summons occurring last year.
This is relevant as the insurance status of a vehicle is checked using automatic number plate recognition technology so the same concerns around the growing use of ghost plates applies.
A more resilient approach to vehicle identity
At SWSC, we continue to invest in advanced, secure technologies to protect motorists and vehicle identity. Our vehicle registration solutions can integrate seamlessly with traditional policing systems, automated detection platforms (including ANPR), and can incorporate RFID-enabled registration devices embedded into windscreens, number plates, or directly onto key vehicle components.
A decision with long-term implications
As Ireland moves towards digital-only verification, ensuring security, traceability, and resilience against criminal exploitation has never been more important. While this shift represents a significant modernisation of public services, the UK experience demonstrates that digital efficiency without adequate safeguards and secure technology can introduce costly and concerning vulnerabilities.
A physical document (such as a tax disc) that is clearly displayed is an easily verifiable way to augment the digital solution and provides a robust solution that the public can rely on in the unfortunate case of bumps on the road.
