QR codes in schools – a useful tool or are they a digital risk?

QR codes have become a common sight in our daily lives – from restaurant menus to NHS check-ins – and schools are increasingly exploring how they can be used to improve communication and access to information. But while they offer clear benefits, there are also growing concerns about their security, particularly in public-facing settings. 

In fact, QR codes have been hitting the headlines recently due to scams — particularly in car parks — where fraudsters have placed fake QR codes over legitimate ones, directing users to phishing websites or payment portals designed to steal personal information. 

This issue came up in a recent conversation we had with a school Trust, which was planning to include QR codes on outdoor banners and signage. After a lengthy discussion and advice from a cybersecurity lead, they made the decision to leave the QR codes off. It’s a small but important example of how even simple digital tools need careful consideration, especially in settings where safeguarding and trust are paramount. 

So, are QR codes right for schools? Here we look at the pros and cons: 

The pros of using QR codes in schools 

Easy access to information 

QR codes offer instant access to digital content – with no need to type long URLs. Whether it’s an event flyer linking to a sign-up form or a banner outside a school pointing to admissions information, QR codes make it easy for families to get what they need quickly. 

Eco-friendly and cost-effective 

Instead of printing multiple leaflets or brochures, schools can use a QR code to link to an up-to-date webpage. This cuts down on paper usage and ensures that families always have the latest information. 

Supports learning 

In the classroom, teachers can use QR codes to direct students to homework resources, videos, or quizzes. They’re particularly useful for younger children who may struggle to type in URLs accurately. 

Engages digital natives 

Today’s students are growing up in a digital-first world. QR codes can be an engaging way to deliver content and encourage tech confidence, especially when used in interactive displays or digital scavenger hunts. 

The cons (and considerations) of using QR codes in schools

Security risks 

QR codes can be vulnerable to misuse. In public settings – such as banners or posters – fake codes could be overlaid, directing users to harmful or misleading sites. While relatively rare, this risk has led some schools and Trusts to advise against using QR codes on external signage. 

Accessibility and access 

Not all families have smartphones or reliable internet access. QR codes may unintentionally exclude some parents and carers, especially in more digitally disadvantaged communities. 

Lack of awareness 

Despite their rise in popularity, some people don’t know how to use QR codes or may be wary of them. This could lead to confusion or lack of engagement with key messages. 

Over-reliance on technology 

As with any digital tool, overuse can become an issue. It’s important not to replace more inclusive or personal communication methods (for example phone calls, printed letters) with QR codes alone. 

My final thoughts 

Used thoughtfully, QR codes can be a valuable addition to a school’s communication and learning toolkit – especially when access is controlled and monitored. However, it’s important to weigh up the benefits against the potential risks, particularly around cybersecurity and accessibility. 

If you’re considering using QR codes in your school, it’s worth creating a simple policy or checklist to ensure they’re used safely and appropriately – and you should always provide an alternative for those who may not be able to scan, such as ensuring a short form URL is printed alongside the code.
