You do not need to add funds to your Visa card to make a payment. The Visa card can't be topped up. It's linked to your wallet, and you can make a payment with it once your wallet is funded.
The amount will be deducted directly from your USD balance.
If your USD balance does not have enough funds, the remaining amount will be taken from your USDC/T wallet balance or any other balance with the highest available funds.
