Mengenal Konstruksi SIM CARD

Sebuah kartu pintar, kartu chip, atau kartu IC, adalah kartu berukuran saku dengan tertanam sirkuit terpadu. Seperti yang dijelaskan dalam standar ISO7816, digunakan dalam telepon selular, TV kabel, kartu ATM, dll

Ada dua kategori besar ICCs. Kartu memori mengandung komponen penyimpanan memori non-volatile, dan mungkin logika keamanan. Kartu mikroprosesor mengandung memori volatile dan
komponen mikroprosesor . Sebuah kartu pintar, kartu chip, atau kartu sirkuit terpadu (ICC) adalah kartu berukuran saku dengan tertanam sirkuit terpadu.

Smart card dapat memberikan identifikasi, otentikasi, penyimpanan data, otentikasi keamanan yang kuat untuk single sign-on (SSO) dan pengolahan aplikasi.

Fisik, listrik dan lainnya karakteristik Smart card dijelaskan oleh ISO / IEC 7810 dan ISO / IEC 7816 seri standar.

Smart Card (SIM Card) pinout


Pin Name Description
C1 VCC +5 VDC power supply input (optional use by the card)
C2 RESET Reset signal, used to reset the card's communications. Either used itself (reset signal supplied from the interface device) or in combination with an interal reset control circuit (optional use by the card). If internal reset is implemented, the voltage supply on Vcc is mandatory
C3 CLOCK Provides the card with a clock signal, from which data communications timing is derived
C4 RESERVED AUX1, optionally used for USB interfaces and other uses.
C5 GND Ground (reference voltage)
C6 Vpp Programing voltage input (optional). This contact may be used to supply the voltage required to program or to erase the internal non-volatile memory. ISO/IEC 7816-3:1997 designated this as a programming voltage: an input for a higher voltage to program persistent memory (e.g., EEPROM). ISO/IEC 7816-3:2006 designates it SPU, for either standard or proprietary use, as input and/or output.
C7 I/O Input or Output for serial data (half-duplex) to the integrated circuit inside the card. 
C8 RESERVED AUX2, optionally used for USB interfaces and other uses.
