Best Practices for Using CVV Numbers Safely

Correct use of your CVV adds extra protection to your card. Refer to the RBI card security guidelines to keep your transactions safe. Also, follow these tips for safety:

Never share your CVV

Trusted websites for online payments

Before you enter CVV, make sure the site uses HTTPS and a safe payment gateway.
