Problems solved by technology

[0005] In order to avoid the dependence of the mobile payment function on the type of mobile phone terminal and realize a complete mobile payment solution on the SIM card, the mainstream dual-interface and full-card solutions inevitably occupy the two reserved contacts C4 and C8. At the same time, the physical positions of the two reserved contacts o

Example Embodiment

[0022] The present invention will be explained in more detail below with the help of embodiments and drawings, but the following embodiments are only illustrative, and the protection scope of the present invention is not limited by these embodiments.

[0023] Such as figure 1 As shown, the telecommunications smart card that implements the NFC function provided by this embodiment includes:

[0024] The card base D, the SIM card module 400 and the antenna layer arranged on the card base D.

[0025] Generally speaking, the card base is the substrate carrying the SIM card chip or the electronic package packaged by the SiP (System in a Package) process; the SIM card contact definition complies with the ISO7816 IC card specification with contacts, and the SIM card module There are 2 reserved contacts and 6 functional contacts (ie C1-C3, C5-C7), of which C1, C2, C3, C5, C7 are conventional SIM card contacts; C1 is used as VCC (Power contact) Provides power for each functional module inside...

Abstract

The invention discloses a telecom smart card for realizing a NFC (Near Field Communication) function, which comprises a card base, an SIM (Subscriber Identity Module) card module and an antenna layer, wherein an NFC chip is embedded in the SIM card module, the SIM card module is arranged on the card base, and two reserved contacts and six functional contacts are arranged on the SIM card module; the antenna layer comprises a coil part, a connecting part and a card contact part which are integrated into a whole, and the card contact part is stuck to the card base. The telecom smart card is characterized in that newly added contacts are arranged in an idle area of the card base, and the NFC chip receives and sends radio frequency signals through two of the newly added contacts and controls a power source and signal transmission respectively through a third newly added contact and a fourth newly added contact. The telecom smart card has the function of the NFC and is compatible with an NFC mobile phone by adding the NFC chips and the contacts. In addition, the problems that reserved contacts in an SIM card are occupied and the contact between the antenna contact and the corresponding contact of the SIM card is poor in the prior art are solved.

Description

Technical field [0001] The invention relates to the field of mobile communication equipment, in particular to a telecommunication smart card containing a near field communication chip. Background technique [0002] Mobile payment, also known as mobile payment, is a service method that allows users to use their mobile terminals (usually mobile phones) to pay for the goods or services they consume. The entire mobile payment value chain includes mobile operators, payment service providers, application providers, equipment providers, system integrators, merchants and end users. At present, most mobile payment services adopt the 13.56MHz and 2.4GHz standards, and the implementation methods mainly include DIC (Dual Interface Card) and NFC (Near Field Communication). [0003] The DIC solution realizes the mobile payment function through the transformation and upgrade of the SIM (Subscriber Identification Module) card, which solves the problem of the mobile payment service based on the NF...
