  • It acts as an extra layer of protection during digital payments.
  • Unlike your card number, CVV is not stored by merchants, which helps reduce fraud.

  • Online shopping (Amazon, Flipkart, etc.)
  • Subscription payments (Netflix, Spotify)
  • Booking tickets (flights, buses, movies)
  • International payments
  • Any card-not-present transaction
