摘要:
A credit transaction system, apparatus, and method are capable of grading credit to other people. The credit transaction system includes a relay unit, a user terminal, and a seller terminal. The relay unit stores credit information including at least one of credit card information and account information of a credit owner, user information and terminal information on a user designated by the credit owner, and credit limit information on a limit usable by the user. The user terminal transmits the user's terminal information to a seller terminal corresponding to the seller. The seller terminal transmits billing records on the goods or service purchased by the user in response to the received user's terminal information. Here, the relay unit performs an authentication process for the user corresponding to the user terminal, and then relays to process payment regarding the billing records via the credit information within the credit limit information.
