Downloading and saving QR codes on your device
Opening your email
Sometimes you’ll get a QR code by email, like a flight ticket, movie ticket, or store coupon. The email might have a QR code as an attachment, like a PDF.
To see your code, you’ll need to open the email app you use, like the Gmail app. If you’ve never used the Gmail app before, do the Android Gmail lesson or the iOS Gmail lesson.
If the QR code is attached to an email, tap on the attachment to open it.

Saving a QR code attachment
It’s a good idea to save the attachment to your device so you can open your QR code even when you don’t have internet access.
Here's what it will look like on your device:
Android: To save the attachment to your device:
- Tap the three dots on the top right corner of the PDF
- Then tap Download
- When you download the attachment, you’ll save it on your device
iOS: To save the attachment to your device:
- Tap the Share button on the bottom of your screen
- Then tap Save to Files
- Select the option On My iPhone by tapping on it
- When you download the attachment, you’ll save it on your device

When you download an app or a file on your device, it saves all the information it needs for you to open and use the app or file.
Opening your QR code
Once you’ve downloaded your QR code, you can open it on your device later.
To open your QR code:
- Look for your Files app on your device’s home screen or app launcher. Here's what it will look like on your device:
- Tap it to open it
- Then tap the three lines on the top left of the screen and tap Downloads. Here's what it will look like on your device:
- Your Downloads folder is sorted by when you saved the files. The attachment you just saved will be the first file in this folder. Tap it to open it.
