So if the XTAL has 3.5712MHz data rate is 9600 Baud, which is one of the standard baud rates. The default data rate for smart cards (ISO7816-3) is f_Clock/372.
Sim card reader software for pc generator#
So a smart card terminal to be used on the serial port just needs a clock generator and level shifting. Formerly it was supply for programming voltage.
That action allows data to be sent TO the SIM.Īnd, when Q1 is off, if the SIM toggles the I/O line then R3 will be pulled low by the SIM (Q1 has nio ffect as it is off) and FTDI-RX line and IC1d both "see" this data from the SIM. When Q1 id off the pin is pulled high by R3. Only on is data related, and that is named "I/O". Look at the circuit names on the SIM card. "Uses a serial port" and the circuit diagram should give you an immense guide.
PC/SC readers use a different (Windows-only) standard, and this reader design will not work with software or hardware that requires PC/SC compatibility Often these are referred to as "phoenix"-type readers. This design uses a serial port to read and write data from a SIM. Is this a Phoenix-compatible SIM card interface? Is this a PC/SC-compatible SIM card interface?.It is found hereĪ lot of the content in your questions would be addressed by readin their FAQ well and/or by looking on web for IM card informatiin. What you should ideally link to, as well as the useful top page, is the circuit diagram., as that is what you are inquiring about.
