Embodiment Construction

[0015] The present invention will be described in more detail below by means of examples and drawings, but the following examples are only illustrative, and the protection scope of the present invention is not limited by these examples.

[0016] Such as figure 1 , figure 2 and image 3 As shown, the telecom smart card that realizes the NFC function in this embodiment includes:

[0017] The card base D, the SIM card module 400 and the antenna layer arranged on the card base D. Wherein, the card base is a base material carrying a smart card chip or an electronic package packaged by a SiP (System in a Package) process.

[0018] Generally speaking, the SIM card pin definition conforms to the ISO7816 integrated circuit card specification with contacts. There are 2 reserved contacts (ie C4 and C8) and 6 functional contacts (ie C1-C3, C5) on the SIM card module. -C7), the five pins C1, C2, C3, C5, and C7 are conventional SIM card pins; C6 has lost its function as VPP (high volta...

Abstract

The invention discloses a telecom intelligent card for realizing a near field communication (NFC) function. The telecom intelligent card comprises a card matrix, a subscriber identity module (SIM) and an antenna layer, wherein an NFC chip is embedded in the SIM; the SIM is arranged on the card matrix and provided with two reserved contacts and six functional contacts; the antenna layer comprises a coil part and a card contacting part; and the card contacting part is adhered to the card matrix. The telecom intelligent card is characterized in that: an area encircled by the six functional contacts is a stressed area in which newly-added contacts are arranged; the NFC chip receives and transmits a radio-frequency signal through the two newly-added contacts; and the coil part, a connecting part and the card contacting part form a whole. The telecom intelligent card realizes the SIM card-based NFC function and solves the problems that the reserved contacts of the SIM are occupied and poor contact exists between an antenna contact and a contact corresponding to the SIM by adding the NFC chip and newly adding contacts in the stressed area.

Description

technical field [0001] The invention relates to the field of mobile communication equipment, in particular to a telecommunications 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 13.56MHz and 2.4GHz standards, and there are mainly two implementation methods: DIC (Dual Interface Card, dual interface card) and NFC (NearField Communication, near field communication). [0003] The DIC solution realizes the mobile payment function through the transformation and upgrading of the SIM (Subscriber Identification Module, personal identificati...
