If you notice unauthorized charges on your card, you can temporarily lock your card right in the app.
On your home screen, tap into your Spend account, then tap "Your Qapital Visa® Debit Card." Here, you'll see the Lock Card toggle. Toggling this on will prevent any charges or withdrawals from your card.
Please reach out to us at support@qapital.com or message us directly in the support section of the app if you have any concerns.
