Be Careful When Scanning QR Codes

The image shows a warning message about scanning QR codes, with “THINK BEFORE SCANNING” in bold red text and a phone screen displaying a “SCAM!” stamp over a QR code.

QR codes have become a part of everyday life. Whether you're pulling up a restaurant menu, checking out event details, or making contactless payments, all you have to do is point your iPhone’s camera at a QR code, and you're instantly connected to a website or action. Quick, easy, and efficient, right? But have you ever stopped to think about the potential risks?

Just like clicking on random links in emails or texts can lead to phishing scams, scanning an unknown QR code can also be risky. There's even a name for this kind of scam: "quishing" (QR code phishing). Although it’s not widespread yet, some reports suggest thousands of cases per month. Fortunately, with a few simple steps, you can stay safe without giving up the convenience of using QR codes.

How to Scan Safely

1. Stick to Trusted Sources

When scanning a QR code, it’s important to be aware of where it’s placed and who provided it. For instance:

Good Example: A QR code printed on the official menu of a restaurant or on a flyer from a trusted organization. It’s clearly meant for customers and comes from a reliable source.

Bad Example: A QR code randomly taped to a signpost or a table without any branding or explanation. These can be risky since anyone could have placed them there with malicious intent.

Always take a second to evaluate the source before scanning.

2. Check the Yellow URL Preview

If you're using an iPhone, after scanning a QR code, Safari shows a yellow preview of the URL. Take a second to glance at this. Does the link look trustworthy? Does it match the business or service you're expecting? If the URL seems odd or unfamiliar, it’s best to avoid clicking it. This simple step can save you from visiting malicious sites.

3. Verify What the Code Does

Before scanning a QR code, consider what you expect it to do—like opening a menu or webpage. If it unexpectedly asks you to log in or prompts something unusual, such as sending an email or launching an app, take a step back. Scammers may use this tactic to steal credentials, so always verify the source and think twice before entering any personal information.

4. Keep iOS Updated

Apple regularly updates iOS to patch security vulnerabilities, including those that can be exploited by malicious QR codes. Installing these updates promptly helps protect your iPhone from potential threats. So, if you see a new update notification, don’t ignore it—your phone’s security could depend on it.

Why You Don’t Need to Worry

It’s important to understand that while “quishing” exists, it’s far from a common occurrence. The vast majority of QR codes you'll scan will be perfectly safe, especially when they come from trusted sources. With a little extra caution, you can continue to enjoy the convenience of QR codes without putting your data or personal information at risk.

Bottom Line

QR codes are a convenient tool, but as with anything online, a bit of awareness goes a long way. Stick to trusted sources, verify the link preview, and keep your phone up to date to stay safe without giving up the ease of scanning.
