Abstract
Disclosed herein are a universal subscriber identification module card and a communication method using the same. The universal subscriber identification module card includes a Universal Subscriber Identification Module (USIM) chip, a pad, and a security chip. The USIM chip performs the user authentication of a mobile terminal. The pad electrically connects the USIM chip to the mobile terminal when the USIM chip is inserted into the mobile terminal. The security chip performs a security function for the mobile terminal independently of the USIM chip and shares the two power terminals of the pad with the USIM chip.
