Abstract: A system and a method are disclosed for conducting a transaction of purchasing goods at online marketplaces including a secure electronic method of credit card information exchange that represents a physical handover of the credit card and return of the credit card. A consumer sends a request to view goods. The system responds with a list of available goods from one or more merchants. The consumer selects an available good and sends a request to purchase it by sending credit card information. The credit card information is encrypted with a public key retrieved from a server, and transmitted to the merchant device. The merchant device decrypts the information using a private key unique to the merchant device. Then credit card information is available at the merchant device for a specific period of time and is destroyed once the time expires or the purchase is marked as complete.
