Patent number: 10128910Abstract: A mobile device with the NFC function includes an NFC chip, multiple SIM card slots, a power supply unit, and an eSE integrated into the NFC chip. One SIM card slot is connected to a first power port on the NFC chip. The power supply unit is connected to a second power port on the NFC chip. When the mobile device performs near field communication, the second power port on the NFC chip is triggered to output a first level signal. Each of the rest SIM card slots is connected to the power supply unit. The eSE is connected to the power supply unit. The power supply unit is configured to supply power to the eSE and the SIM card slot that is connected to the power supply unit, when the first level signal is received.Type: GrantFiled: May 15, 2015Date of Patent: November 13, 2018Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Zhonghui Peng, Heng Wang, Yonggang Wang, Dongjin Chen, Yang Gao
