QR codes have become a popular, convenient way to make payments, but they also open the door to scams. This was seen in a recent incident where someone lost €1,000 after scanning a QR code for parking, which redirected to a fraudulent payment page.
Scammers can easily place fake QR codes over legitimate ones, tricking users into entering sensitive information or making unauthorized payments.
It is advisable to always double-check the URL after scanning; if it appears suspicious, do not proceed.

QR code scams are fraudulent schemes where scammers use QR codes to trick people into providing personal information, installing malware, or making unauthorized payments. Here are some common types of QR code scams and how they work:
1. Phishing via QR Codes
- How it works: Scammers create QR codes that redirect to fake websites designed to look like legitimate sites. Once scanned, users may be prompted to enter sensitive information like login credentials, credit card details, or personal information.
- Example: A QR code on a poster claims to offer a discount on a popular brand. When scanned, it takes the user to a fake website that asks for payment details.
2. Malware Distribution
- How it works: Scanning the QR code triggers the download of malicious software onto the user’s device. This malware can steal data, monitor activities, or even lock the device and demand a ransom.
- Example: A QR code is advertised as a link to a free app download, but instead, it installs malware on the user’s phone.
3. Payment Scams
- How it works: Scammers replace legitimate QR codes with their own, redirecting payments to their accounts instead of the intended recipient. This is often seen in places where QR codes are used for payments, such as restaurants or parking meters.
- Example: A restaurant’s QR code on a menu for paying the bill is swapped with a fraudulent one, and payments go directly to the scammer.
4. Fake Customer Support or Verification
- How it works: Scammers may place fake QR codes on receipts, invoices, or emails that claim to provide customer support or verify your account. When scanned, it may lead to phishing websites or prompt users to provide sensitive information.
- Example: A QR code on an invoice claims to be for verifying a payment, but it leads to a fake customer service page that asks for bank account details.
5. Social Media and Giveaway Scams
- How it works: Scammers promote QR codes on social media, claiming they lead to exclusive content, discounts, or giveaway entries. Users who scan the code may end up on a phishing site or be tricked into providing personal information.
- Example: A social media post advertises a giveaway; the QR code leads to a site asking for personal details or a small fee to “claim the prize.”
How to Protect Yourself
- Be cautious of QR codes in public spaces: Verify the source before scanning, especially if it’s printed on posters, flyers, or business cards.
- Check for tampering: Look closely to see if the QR code has been pasted over another one.
- Use a QR code scanner with safety features: Some apps can check URLs before opening them, alerting users if they lead to suspicious sites.
- Enable app permissions carefully: Be wary of QR codes that prompt you to download apps or enable permissions.
- Verify URLs before providing information: If you’re redirected to a website, double-check the URL for signs of phishing.
