When you sign up for a Switch Visa Card, you will need to activate the card so you can use the digital card while the physical card ships to you. To set your card pin, navigate to the Profile Screen 
, click "Card Information".
An alert will pop up to activate your card. Then you can select "Change Card Pin" to set your Pin number for the Switch Visa Card.
Once this is complete you can then add your Switch Visa Card to your Apple Pay® or Google Pay ™.
