The customer must be logged in using the same email address provided when products were added to the cart.\n\nWhen you choose to enable this field, [SmartCheckout](/en/docs/tutorials/smartcheckout-security) will be disabled for all your customers.\n\n## Minimum time between orders\n\nBy setting a numeric value for the `minimumPurchaseDowntimeSeconds` field, you can determine the minimum time in seconds a buyer must wait before placing another order. This setting prevents customers from creating multiple orders in a short time.\n\nWe recommend setting this field to 90 seconds and using this setting in combination with [Require login when placing an order](#require-login-when-placing-an-order).\n\n## Minimum time for a cart to exist before a new credit card can be used\n\nSetting a numeric value in the `cartAgeToUseNewCardSeconds` field specifies how many seconds a new cart needs to exist before a new credit card can be used.\n\nThis setting reduces the risk of creating multiple carts and adding new credit cards. Activating this field does not affect orders placed with cards previously saved in the customer account.\n\nWe recommend setting this field to 30 seconds.\n\n### Require login to add a new credit card\n\nWhen the `requiresLoginToUseNewCard` field is set to `true`, the system requires the customer to be logged into the store in order to add a new credit card as a payment method. This setting enhances transaction security and helps prevent unauthorized use of credit cards."}
