Movable terminal, NFC device supporting a plurality of SIM cards and implementation method

Abstract

The invention discloses an NFC device supporting a plurality of SIM cards, comprising an NFC chip, an SWP switch and a main control module. The NFC chip is used for establishing data connection with an external card-reading device and acquiring data information including operator identifications supported by the card-reading device; the SWP switch is used for connecting one of a plurality of SIM cards to the NFC chip; and the main control module is used for controlling the SWP switch to select an operator SIM card supported by the card-reading device according to the operator identifications supported by the card-reading device and connecting the NFC chip with the SIM card. The invention also discloses an NFC implementation method supporting a plurality of SIM cards and a mobile terminal,decreases the cost by only using one NFC chip and automatically selects the SIM card connected with the NFC chip according to the acquired operator identifications supported by the card-reading device.

Description

technical field [0001] The invention relates to the communication field, in particular to an NFC device supporting multiple SIM cards, an NFC implementation method supporting multiple SIM cards, and a mobile terminal. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for the quality of life. In order to meet the needs of short-distance communication between electronic devices, Philips, Nokia, Sony and other famous manufacturers jointly launched a new wireless communication technology NFC (Near Field Communication, short-range wireless communication technology), compared with other short-range communication technologies, NFC has distinctive features such as short distance, low energy consumption, more security, and compatibility with existing contactless smart card technology. The NFC technology is widely used It is used on terminal equipment to make the mutual access between terminal equipment more ...

AI Technical Summary

Problems solved by technology

The terminal equipment of the prior art realizes the card swiping operation with the external POS (point of sale, point of sale terminal) machine through the SIM (Subscriber Identity Module, user identity module) card of the terminal connected to the NFC chip, while the existing reader There are many operators supported by the card device, and each SIM card can only correspond to one operator, so in the prior art, multiple SIM cards are installed on the terminal equipment to realize the selection and use of SIM cards of multiple operators. And each SIM card corresponds to an NFC chip, resulting in an increase in cost. At the same time, the switching between different SIM cards is mainly realized manually, which makes the user troublesome to use and is very inconvenient.
