ReferenceGlossaryCIT & MITOn this page🔄 CIT & MIT Definition​ In payment processing, transactions are categorized as either Client Initiated Transactions (CIT) or Merchant Initiated Transactions (MIT). CIT (Client Initiated Transaction): A transaction triggered by the customer, where they actively provide their payment details and authenticate the transaction (e.g., entering a card number and confirming with 3D Secure). MIT (Merchant Initiated Transaction): A transaction initiated by the merchant, based on a prior agreement with the customer, without direct interaction at the time of payment (e.g., a recurring subscription or delayed charge). - Key Differences:​ FeatureCIT (Client-Initiated)MIT (Merchant-Initiated)User InteractionRequiredNot requiredAuthenticationStrong authentication RequiredBased on prior agreementUse CasesOnline purchases, POS transactionsSubscriptions, delayed charges
