If you start with the program Dump.py which purpose is to read the contents of a Mifare1K card you will see that is uses this function: https://github.com/mxgxw/MFRC522-python/blob/master/MFRC522.py#L392 This function assumes that Key A is the "read" key so it authenticates with that before calling...

I have used basic libraries available on Github.

Can you at least point to the code you are using ? Right now I dont even know what programming language you use.

Here it is. I am using python

https://github.com/mxgxw/MFRC522-python

As you stated """But if you need to securely program the readers with the key so that the software never needs the keys during operation then you have to do it the other way. ( But Mifare security is completely broken. so any attempt to seriously protect the CRYPTO1 A/B keys are more or less futile ...

I have successfully connected MFRC522 based card reader to RPi and now I want to decrypt each individual sector of a 4kb card with individual sector keys. Does anyone has good example codes/links for how can it be done? My work is mainly on the basic study of RFID using Raspberry Pi. The keys may ei...

Hello all, I am working on MFRC522 RFID and I have connected a reader via SPI port to the Rpi board. I am able to do basic UID reading. But I am working on a college project where I need to put the sector keys in MFRC522 reader breakout board chip(RC522) / or decode each data sectors with individual...

That blog link looks like a decent guide. Are you able to follow it down to and including the "pcsc_scan" step ? Waiting for card. No output.... Later I found the same card reader had counterfeit PL2303 chip. I am thinking of making a hardware with original PL2303 breakout board , 3.57MHz clock gen...

The question is what is on the other side of the PL2303, what kind of documentation do you have ? If its using serial port then it is not USB-CCID compatible, byt it might still use some know protocol, but you have to figure out which by reading the documentation I guess. Hi, I am new to this....so...

Most likely yes.. a SIM card is just a Smartcard after all. You need a reader compatible with CCID, then installing "pcscd" should add the necessary "drivers"/libraries. Python for PCSC https://pyscard.sourceforge.io/ So I finally received it, installed driver , yet the setup is not being detected ...

Thanks. Waiting for USB reader to be delivered. Will do as suggested.

Can a generic USB SIM card reader be used as Smart Card reader ? Where can I find drivers and python libraries for the same ?
I wish to use USB port if the RPi for the same. Please guide.

I accidentally shorted Raspberry pi 3B+ , 3.3V pin 1 to ground. Now the MXL7704 regulator's pin 25 or 3.3V pin seems internally shorted to ground. Is there any fix, how to reset the power management chip....or is my Pi fried ?
