Case Study (SET)
  • I browse Web, select Merchant, select Item
  • I choose to make a payment with my electronic wallet
  • The Merchant server sends an order to my Web browser to open my wallet
  • My wallet exchange handshake messages with the server
    • confirms that the Merchant is authorized to process payments with my CC
    • confirms to the Merchant that I am an authorized card holder
  • My wallet constructs the Purchase Order and payment instruction (cryptographically protected)
  • Payment instruction is sent to the Merchant gateway server (usually run by the Merchant's bank)
  • My wallet receives purchase-response message. This ends the electronic payment procedure
