To find out if your card is verified, tap on your card and scroll to the bottom.
If you see a red box under the 'Notes' section, it means your card is not yet verified. Tap on the red box to send an email to verify your card.
If the red box is not there, it means your card has been successfully verified.
PS. If you recently verified your card and it still shows as 'unverfied' - try opening the app, and in the main screen (the card list) and 'pull down to refresh' - your card should appear as verified now.
