We’re familiar with QR codes now in our everyday life for products and services. From purchasing tickets or ordering food at restaurants, to paying for parking or just connecting to Wi-Fi…they have become a part of our lives for quick and easy access to websites.
QR (Quick Response) codes are like barcodes. When we scan them with a mobile phone camera, a link to the information they hold appears. Whilst providing us with a quick and easy way to access information, not all of them are secure. Cyber criminals can use QR codes to steal personal and bank details.
However, there are ways to protect yourself from this fraud.
QR phishing, also known as ‘quishing’ uses malicious QR codes to send users to a fraudulent website or prompt a download of harmful software that spreads malware or prompts the sharing of confidential information.
• Cyber criminals posing as real companies send phishing emails with a QR code and ask users to scan it. Then, they attempt to obtain information or spread virus-infected files.
• Another common scam is the false QR code stuck on top of an original one, like in restaurants or street advertising. False QR codes can even be found on parking meters, linking to a credible but fake payment site to steal money or credit card information.
• Scammers using inverted QR codes firstly create a malicious code and then use it as a presumed payment method. But the code does exactly the opposite: it requests money from the user. This type of scam is also used to steal personal information and bank details.
How to avoid a QR scam
• Before scanning a QR code, like in a restaurant or a public space, check that it hasn’t been tampered with or got a sticker placed over an original code.
• Installing anti-virus software for your device will help you avoid having a virus or other malware downloaded onto your mobile.
• Check the preview of the QR code link. When you scan a QR code, a preview of the URL should display on your device. Make sure the website address is legitimate. Look for a padlock symbol and an address that begins with “https://”. Only those URLs are secure.
• Think twice if the app or website you’re being directed to ask you to provide personal details. If it does, make sure it’s authentic.
• Scanning QR codes in open spaces (like stations and car parks) might be riskier. As with many cyber attacks, you should be suspicious if you’re asked to provide what feels like too much information, whether that’s on a website or in any follow-up communications (such as a phone call).

We celebrate our new branch opening in Harpenden
We are thrilled to announce the launch of our brand-new branch, located right on the High Street, in one of the busiest areas of Harpenden. The doors opened on the 15th of January, with the event being kicked off by celebrations and excitement from colleagues and members alike. Local members were offered the chance to visit and be a VIP guest to see the grand opening and were greeted by some food and hot drinks while they got to have a look around the new branch or ask our branch team any questions that they had. It was lovely to see so many members come and show their support for us. Also there to show their support were colleagues from the Harpenden Hopper, a local charity that we have supported for a few years. We were also joined by both the Mayor of Harpenden as well as our local MP. After some lovely speeches from our Chair and the Mayor all about the community-focus of the branch, the ribbon was cut, and our new Harpenden branch was declared officially open. You might notice a refreshed look to our brand both inside and outside the building. Our new branch aims to deliver confidence to our members. Being a mutual, our focus will always be about putting our members first. The branch is a nod to our heritage within Harpenden, as well as our renewed commitment to the community and our members. The customer experience is always at the front of our minds, and the new branch has been designed with this in mind. The colourful interior, while looking refreshed and playful, creates a welcoming atmosphere for our friendly branch team to help customers in the best way they can. This branch also comes with a technical upgrade, with iPads and digital screens to aid in the member's experience. With these new upgrades, we can assure our members that the clarity and trust they hold with the Society is still there and isn't going away any time soon. Our branch colleagues are as can-do and helpful as ever, but with a larger and more prominent location, we are setting our sights on an improved future. Tracie Meadows, the CEO of Harpenden Building Society said: "We at Harpenden Building Society always put our members first. Our new branch is just that. It's us giving back to our members and the community in Harpenden." She continued that, "We're giving our customers a better experience, while still being the friendly building society that's always ready to lend a hand. We want people to leave the branch feeling confident in us, and in their financial decisions." Our new Harpenden branch represents an exciting next step for the Society, and is just the beginning - there's definitely more to look forward to in the future.
