What Is a QR Code?

A QR code is a square code that opens a link, menu, or app.

A QR code is a little square pattern that a phone camera can read. It is like a shortcut to a website or some information.

Adults scan them everywhere to save time: restaurant menus, event tickets, websites, Wi-Fi setup, payment links, and product info.

It is easy as 1-2-3-4: open your camera, point it at the QR code, your phone reads it, and a link or action pops up.

But are they all okay? No. Most QR codes are safe and helpful, but some can send you to fake or tricky websites.

So the smart move is to always check where the link goes before tapping it, the same way you would check any link.

Remember: QR codes are shortcuts. Ask a grown-up, check the website name, and do not scan random codes just because they are there. A QR code can be helpful, but be careful.

What to remember

  • A QR code is a shortcut a camera can read.

For grown-ups

A QR code encodes a URL or action a camera resolves instantly, which is exactly why 'quishing' (QR phishing) works: the destination is hidden until you tap. Preview the URL before opening, be wary of stickers placed over real codes on parking meters or posters, and treat unexpected payment QR codes with suspicion.
