Beginner QR Code iPhone Android How-To

QR codes are on everything — restaurant menus, product labels, business cards, event tickets, WiFi passwords, payment terminals. But how do you actually scan them? The good news: your phone can do it without any extra app.

How to Scan on iPhone

Method 1: Camera App (Easiest)

  1. Open the Camera app
  2. Point it at the QR code
  3. A notification banner appears at the top
  4. Tap the banner to open the link

That is it. No extra app needed — the Camera app has built-in QR scanning since iOS 11.

Method 2: Control Center Scanner

  1. Open Control Center (swipe down from top-right)
  2. Tap the QR code scanner icon
  3. Point at the code
  4. It scans and opens automatically

If you do not see the QR icon in Control Center: Settings → Control Center → add Code Scanner.

Method 3: From a Photo

If the QR code is in a screenshot or saved image:

  1. Open the photo in Photos
  2. Long-press on the QR code in the image
  3. Tap Open in Safari

Or use Live Text: open the photo, tap the QR code, and iOS recognizes it automatically.

How to Scan on Android

Method 1: Camera App

Most Android phones (2018+) have built-in QR scanning:

  1. Open the Camera app
  2. Point at the QR code
  3. A link or popup appears
  4. Tap to open

If your camera does not detect QR codes, enable it: Camera settings → Scan QR codes → On.

Method 2: Google Lens

  1. Open the Google app or Google Lens
  2. Tap the camera/lens icon
  3. Point at the QR code
  4. Tap the result

Method 3: Quick Settings

Some Android phones have a QR scanner in Quick Settings:

  1. Swipe down twice from the top
  2. Look for QR Scanner or Scan QR code
  3. Tap it and point your camera

Method 4: From a Photo

  1. Open the image in Google Photos
  2. Tap Lens (the Google Lens icon)
  3. It detects and reads the QR code

How to Scan on Computer (No Camera)

If the QR code is on your screen (in an email, website, or document) and you need to read it without a phone:

Chrome Extension

Install "QR Code Reader" extension → right-click any QR code image → "Read QR Code"

Online Tool

  1. Take a screenshot of the QR code
  2. Upload to an online QR reader
  3. Get the decoded content

Manual Decode

Right-click the QR code image → "Copy image address" or "Save image" — sometimes the URL is already in the image filename or alt text.

What Can QR Codes Do?

When you scan a QR code, it can:

Content What Happens
URL Opens the website
WiFi Connects to the network automatically
Phone number Opens dialer
Email Opens email composer
Text Displays the text
Location Opens maps
Payment Opens payment app
App download Opens app store
Calendar event Adds to calendar
Contact (vCard) Adds to contacts

QR Code Safety

Before You Scan

  • Check the source — do not scan random QR codes from stickers on street poles or public restrooms
  • Preview the URL — most phones show the URL before opening. Check if it looks legitimate
  • Be suspicious of stickers — scammers place their QR stickers over legitimate ones (e.g., on parking meters, restaurant tables)
  • Never enter credentials — if a QR code leads to a login page, go to the website directly instead

Red Flags

  • QR code is a sticker placed over another QR code
  • URL looks suspicious or misspelled
  • The link asks for personal information immediately
  • The QR code is on an unsolicited flyer or handout
