Example Embodiment

[0017] Embodiment 1. In order to solve the above-mentioned pin connection problem between the NFC chip and the SIM card, in specific implementation, the inventor considers that the SIM card tray of the mobile terminal (such as Iphone5) needs to be improved, such as figure 2 As shown, the external device of the mobile terminal in this embodiment includes: a SIM card holder 22 that can carry a SIM card 21 of the mobile terminal and can be inserted into the SIM card slot of the mobile terminal, an NFC chip 23, and an NFC antenna 24; among them, the SIM The card tray 22 leads the C1 pin 211, C5 pin 212 and C6 pin 213 of the SIM card 21 of the mobile terminal to the outer wall of the SIM card tray 22, and forms corresponding three internal contacts respectively 221, 222, 223, that is, C1 pin 211 corresponds to internal contact 221, C5 pin 212 corresponds to internal contact 222, C6 pin 213 corresponds to internal contact 223; C1 pin 211, C5 pin 212 and C6 pin 213 pass the correspondi...

Example Embodiment

[0018] Embodiment 2. In order to facilitate the pin connection of the NFC chip and the SIM card, see image 3 As shown, this embodiment is optimized on the basis of embodiment 1, which includes: a SIM card holder 32 that can carry a SIM card 31 of a mobile terminal and can be inserted into the SIM card slot of the mobile terminal, an NFC chip 33, and NFC Antenna 34; Among them, the NFC chip 33 and the NFC antenna 34 are integrated on a housing 35 that matches the mobile terminal, and the housing 35 is also provided with three external contacts connected to the NFC chip 33, namely 351, 352, and 353. The SIM card tray 32 leads the C1 pin 311, C5 pin 312, and C6 pin 313 of the mobile terminal SIM card 31 to the outer wall of the SIM card tray 32, and forms corresponding three internal contacts 321 and 322 respectively. , 323, that is, the C1 pin 311 corresponds to the internal contact 321, the C5 pin 312 corresponds to the internal contact 322, and the C6 pin 313 corresponds to th...

Abstract

The invention provides an external device of a mobile terminal. The external device is used for solving the problems that most of current mobile terminals do not have an NFC-SWP function and are high in replacement cost. The external device of the mobile terminal comprises an SIM card tray, an NFC chip and an NFC antenna, wherein the SIM card tray can bear an SIM card of the mobile terminal and can be inserted into an SIM card position of the mobile terminal; the SIM card tray leads a pin C1, a pin C5 and a pin C6 of the SIM card of the mobile terminal to the outer wall of the SIM card tray, and forms three internal contacts correspondingly; the pin C1, the pin C5 and the pin C6 are connected with the NFC chip through the corresponding internal contacts; and the NFC antenna is connected with the NFC chip. The external device provided by the invention can enable a mobile terminal without an NFC function to have the NFC-SWP function at an extremely low cost. The external device provided by the invention reduces the application cost for users and is more conducive to popularization of NFC near field payment for the operators.

Description

【Technical field】 [0001] The invention relates to the field of wireless communication, in particular to an external device of a mobile terminal. 【Background technique】 [0002] NFC (Near Field Communication) is an emerging technology that has developed rapidly in recent years. It was proposed by Sony, Philips and Nokia. It enables two electronic devices to directly communicate with each other in a short distance. It works in the 13.56MHz frequency band and has a working distance of a few centimeters. The goal of NFC technology is short-distance communication between electronic devices, and it mainly realizes three types of functions: non-contact IC card simulation function; point-to-point data communication function; card reader function. The emergence of NFC technology has greatly promoted the integration of RFID (Radio Frequency Identification) technology and mobile communication technology, leading to many new application modes. [0003] On December 14, 2012, the centra...
