A mail order / telephone order (MOTO) is a transaction initiated via mail order or over the phone.
If you accept card payments from your customers over the phone and process those payments through Stripe, those payments would be categorized as MOTO transactions, which fall outside the scope of Strong Customer Authentication (SCA) requirements.
Keyed-in transactions, which are card transactions where you key in the card number, expiration date, and security code to a card machine, are often used when you do not have access to the physical card. In those circumstances, these transactions might be MOTO transactions.
If your account is in the European Economic Area, payments made by manually entering card details in the Dashboard will be automatically marked as MOTO by Stripe. If you need to process phone and mail payments via the API, contact us to enable this feature on your Stripe account.
