The key components of Secure Electronic Transactions

  • Merchant server. The online merchant's server facilitates communication between the customer and the payment gateway for the transaction.
  • Payment gateway. It securely transmits payment information as an intermediary between the customer's bank and the merchant.
  • Certification authority (CA). The CA issues digital certificates to verify the identities of the entities involved (customer, merchant, payment gateway).
  • Cardholder wallet. The digital wallet securely stores the customer's payment card information.
