Freezing your card temporarily stops it working:

• at cash machines
• for online payments and purchases
• with Apple and Google Pay
• for card subscriptions (like Netflix)
• with a card reader (e.g. confirm a new payment)

However, you can still top up your frozen card from your main wallet.

Find the card you want to freeze in the Wallets section.

Open the card and click Freeze and enter 2FA code to confirm.

Unfreeze card

Open the card you want to unfreeze and click"Unfreeze"and enter 2FA code to confirm. 

Alternatively, hover over a frozen card and click unfreeze
