How do I use the cylinder scanning feature?

Press the 'scanner' button along the top of the app.

If you have not already signed in, you will be asked to now.

The camera feature will then be enabled on your phone. Position the red vertical line shown on screen on the barcode on the cylinder you wish to reorder

The barcode will automatically be scanned, and the cylinder will be placed in your shopping cart.

You can then either scan another cylinder, or go to your shopping cart.
