It would be faster and easier for a Short URL in place of a QR code in most cases.

For example - at the bus stop with a QR code I would have:

- locate an app I rarely use in the Menu

- open app

- depending on app, hit button to go to camera

- snap photo

- processing time

- opens web browser... (sometimes I'd get a confirmation page prior to the action)

With a Short URL:

- open browser thats prominently placed on my phone

- tap in Short URL (bit.ly/xYz123XyZ)

Manually typing a Short URL is a very low pain point in comparison to QR codes these days.
