A QR Action is a great way to share an app, URL, or Action person-to-person
The user apps the action to see a larger version of the QR code. Then scan the QR code to open the designated app, URL, or Action.
If you add a URL or other text string in the URL field, then a QR code will be generated to match that string.
Special use cases:
Marketing use case to capture phone numbers from contacts: The QR code format to launch a text message from the scanning phone is: "SMSTO:number: text message" Thus for, if your mobile number is 555-555-1212 and your app URL is https://pwa.to/myapp, then add the string:
SMSTO:5555551212:Let's connect! https://pwa.to/myapp
to the QR field and you will get a QR code that, when scanned by a prospect, will launch a text message back to you and leave you both with each other's phone number and with a link to your app.
Payment QR: Add your Venmo payment URL to easily display your Venmo QR for payment.
As with most other actions, you can customize the call-to-action and its format.
