Yes, as soon as you get your Visa card, you will have to activate it online or over phone by following the instructions on the card sticker. It usually takes 5 to 10 business days for the Visa card to come but no money will be on there. Once the IRS approves and issues your refund, your refund will be deposited directly to your Visa Card account.
