What is the correct name for this chip? And how to read it?
This is a smart-card contact interface. They don't have a specific name, but they are specified in the ISO/IEC 7816-2. 

You'll find the electrical protocol specified in ISO 7816-3. In a nutshell it is not too different to RS232 serial communication with the difference that the RX and TX lines are shared on one pin, and that a multiple of the baud rate has to be provided as an external clock.

You can buy reader devices pretty much anywhere.
