This reader follows a so-called Phoenix design, in which a 3.579 MHz crystal is used in combination with two inverters of a 74HC08 to clock the card, while two other inverters and a transistor are used to connect the data line to a RS232 port. The schematics are probably very close to [
Also there are two different kind of $2 transparent blue sim card readers on ebay: One is dark blue and the other is light blue. I ordered both of them, the dark one is working with exactly the same output as in this tutorial. The lighter one did not arrive until now.
I see other problem with this SIM card reader that if we remove and insert then nothing work even will kill openct and pcscd. The only way I found that purge and autoremove all the packages and restart the PC and then follow the instructions again.
