With your Visa Debit card, you can sign for your purchases, or in some cases enter a PIN when a merchant provides a PIN pad. In other instances, you can pay without signing or entering a PIN, generally for purchases below $25 (or below $50 at grocery stores).
When you sign for your purchases, you get security protections that help prevent, detect and resolve fraud. Many rewards programs also require you to sign to collect rewards points. You will also receive added security protection for online, phone and mail orders, and for transactions up to $50 that don't require your signature.
If you’re using your card with a PIN pad or terminal, you may still be able to sign for your transaction. On some terminals, you may be required to swipe or insert your card without selecting CREDIT/DEBIT. In these cases, you may press CANCEL to sign or tell the cashier you want to sign for your purchase.
When you press CREDIT for a Visa Debit card transaction, you do not pay a credit card fee or interest. Your Visa Debit card still works like a debit card, not a credit card.
If you use your PIN for your Visa Debit card transactions without signing, you may not receive the same security protections for transactions not processed by Visa.
