Embodiment Construction

[0015] refer to figure 1 , figure 1 is a circuit diagram of a preferred embodiment of the mobile phone of the present invention. The mobile phone of the present invention includes an NFC chip P, a first capacitor C1, a second capacitor C2, a first switch element Q1, a second switch element Q2, a first resistor R1, a second resistor R2, a first light source L1 and a second light source L2 .

[0016] The NFC chip P includes a control pin K, a first pin VHDF and a second pin TVDD. When the mobile phone is close to the card reader to be used as a card, the NFC chip P needs to realize the card simulation function. At this time, the card reader will emit a magnetic field, and generally the matching frequency of the magnetic field is 13.56MHZ. The NFC chip P close to the card reader will sense this magnetic field through the NFC antenna (not shown) of the mobile phone, so that the first voltage will be output on the first pin VDHF. When the mobile phone is used as a card reader,...

Abstract

The invention discloses a mobile phone. The mobile phone comprises a near field communication (NFC) chip, a first switch element, a second switch element, a first light source and a second light source. The NFC chip comprises a first pin and a second pin, wherein the first pin output a first voltage when the NFC chip functions as card analog, and the second pin outputs a second voltage when the NFC chip functions as a card reader. The first end of the first switch element is connected with the first pin, and the second end of the first switch element is earthed. The first end of the second switch element is connected with the second pin, and the second end of the second switch element is earthed. One end of the first light source is connected with the third end of the first switch element, and the other end of the first light source is connected with a third voltage. One end of the second light source is connected with the third end of the second switch element, and the other end of the second light source is connected with the third voltage. The first switch element is turned on under the action of the first voltage to make the first light source emit light, and the second switch element is turned on under the action of the second voltage to make the second light source emit light. Thus, when the mobile phone of the invention is used, a user can easily know the type of the current NFC function of the mobile phone through an indicator lamp.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a mobile phone. Background technique [0002] With the development of communication technology, mobile phones have become a communication tool that people carry with them. Moreover, integrating the NFC (Near Field Communication) function on the mobile phone greatly facilitates the user to use the NFC function, such as bus card swiping, small electronic payment and so on. A mobile phone with NFC function can not only have the function of a card reader, but also can be read in the form of a card, that is, the card simulation function. However, in existing mobile phones, there is no indication method with NFC function, and it is impossible to easily know the type of the current NFC function of the mobile phone, that is, the user cannot easily know whether the mobile phone is currently used as a card reader or as a card. [0003] Therefore, it is urgent to provide a mobile pho...
