Once you've received your Found card, you can activate it online with a couple of clicks:
Log into your Found account
Select the debit card in the Cards tab
Click Activate.
Enter the last four digits of your card number and your card will be made active.
If you ever need to deactivate your Found card, you can do so by tapping the debit card icon in your Found app, then toggling the “Enable card” setting.
