Welcome! Let's Talk About QR Codes

Hi there! I'm Skits, and I'll be your guide today.

Have you noticed those little square patterns showing up everywhere? On restaurant tables, flyers, business cards, even on TV? Those are QR codes, and they're way simpler than they look. By the end of this course, you'll be scanning them like you've done it your whole life.

But first — what's your name?

What Is a QR Code?

A QR code is just a shortcut. Instead of typing a long web address into your phone, you point your camera at the code and it takes you there automatically. That's it. No app to download (on most phones), no account to create, no password to remember.

QR stands for "Quick Response" — because it's meant to be fast. Point, scan, done.

Scanning a QR code at a coffee shop — a real-world example of how QR codes are used every day

Think of it like a barcode at the grocery store. The cashier scans it and the computer knows what the product is. A QR code works the same way, except instead of a price, it usually opens a website on your phone.

In This Course, You'll Learn:

How to scan a QR code on an iPhone
How to scan a QR code on an Android phone
Where you'll run into QR codes in everyday life
How to stay safe — yes, there are scam QR codes
What to do when a scan doesn't work

And the best part? You'll actually practice scanning real QR codes during this course, right from your phone. So grab it and keep it nearby!

What QR Codes Actually Do

They're just links in disguise.

A QR code is really just a web address (or other information) turned into a pattern your phone's camera can read. When you scan one, your phone reads the pattern, figures out what it says, and shows you where it wants to take you.

What Can a QR Code Link To?

Most QR codes take you to a website, but they can do other things too:

🍲

A Restaurant Menu

Instead of a paper menu, you scan the code on the table and the menu pops up on your phone.

🌐

A Website

A flyer with a QR code might take you straight to a business's website — no typing required.

👤

A Contact Card

Scan a QR code on someone's business card and their name, phone number, and website save right to your phone's contacts. No typing anything.

📞

A Phone Number

Some QR codes dial a phone number for you. One tap and you're calling.

📧

An Email Address

Scan the code and a new email opens, already addressed and ready to send.

🗺

A Map Location

Scan a code on an invitation and it opens directions right in your Maps app.

💳

A Payment

Some businesses let you pay by scanning a QR code. Very common at farmers' markets and small shops.

The important thing to know: Your phone always shows you where a QR code wants to take you before it goes there. You get to decide whether to tap the link or not. You're always in control.
