This causes different outcomes depending on the card type:\n\n- **Credit Card:** The transaction fails to start and an error is shown at checkout before it is sent to provider\n- **Debit Card:** The transaction starts and it is sent to provider without card security code\n\n## Simulation\n\n1. Create a cart and complete profile and logistics info until you reach the payment step.\n2. Fill in card details on the native card interface (credit or debit).\n3. Switch to a different payment method.\n4. Switch back to the card from step 2 — notice the security code field still looks filled.\n5. Complete any remaining required fields without touching the security code.\n6. Attempt to place the order.\n\n## Workaround\n\nAfter switching payment methods, clear the security code field and re-enter it before placing the order."}
