Abstract: Provided is a mobile terminal that has a function of changing a payment credit card at the time of near field communication (NFC) payment in a low battery state, and a method of performing the NFC payment using the mobile terminal. In the mobile terminal according to the present invention, unlike in a mobile terminal in the related art in which payment is simply performed with a default credit card, if the NFC payment is requested in the low battery state where the mobile terminal is powered off, a payment application based on a light operating system, which is executed on an embedded Linux, is displayed, and the NFC payment with a credit card selected from the payment application based on the corresponding light operating system is performed. Therefore, a credit card payment can be effectively performed in a low battery state as well.
