A log-in system for web page access in a vehicular platform using a NFC terminal is provided. The system includes a computer (PC) that stores and manages addresses of web pages that the user has accessed and personal information such as identification (ID) and a password required to log-in for each corresponding web page in a user database (DB). A server receives registration for log-in information from at least one computer via the Internet and manages the log-in information accordingly. A portable terminal having an NFC function downloads and stores information for the web pages, which have been accessed by the portable terminal, and log-in information from the computer or the server. A vehicle platform then receives the log-in information stored in the portable terminal via NFC and automatically executes log-in for an Internet web page based on the log-in information.
