No. SCA UK does not hold bank or card details in Beacon.
Our payments are handled separately by companies such as PayPal, Stripe and GoCardless, and none of those is affected by this incident. You do not need to cancel a Direct Debit, change a card, or contact your bank because of this.
What Beacon does hold is a record that a donation was made, including the amount and the date. That is not the same as your payment details.
