This tutorial will help you to identify your smart card and its connections
A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits which can process data. This implies that it can receive input which is processed — by way of the ICC applications — and delivered as an output. There are two broad categories of ICCs. Memory cards contain only non-volatile memory storage components, and perhaps some specific security logic. Microprocessor cards contain volatile memory and microprocessor components. The card is made of plastic, generally PVC, but sometimes ABS. The card may embed a hologram to avoid counterfeiting. Using smart cards is also a form of strong security authentication for single sign-on within large companies and organizations.
Described by ISO 7816 standard. Used in cellular phones, pay TVs, etc.
|1||VCC||+5 VDC power supply input (optional use by the card)|
|2||RESET||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|
|3||CLOCK||Clocking or timing signal (optional use by the card)|
|4||GND||Ground (reference voltage)|
|5||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.|
|6||I/O||Input or Output for serial data to the integrated circuit inside the card|
Also as you can see I2C Smart card pinout
As you can see in the following image, there are a lot of smart cards and SIM cards pads shapes:
