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...
