Mifare Desfire / Mifare plus can't read with ACS ACR1252

Question

Hi i'm newbie in RFID reading. So firstly i downloaded pcsc sharp repository from github. Then i tried to read binary from common rfid tag, it works perfect but the next step was to read data from as i think emulated rfid tag. RFID tag controller is pn71501. From this tag using pcsc sharp i can't read any data excluding ATR and uid. I tried to read this tag using my iPhone and it read it. So what i'm doing wrong?

I also tried to use already done software but it couldn't read it also.

Here is what i get using NFC Tools:

PS Smart Card reader i used is ACS ACR1252

Here is my code:

Answer 1

I know. I looked it up earlier. Can you read the card with the file explorer?

A hardware device like a UART can be read at three different levels

1. Read/Write UART directly by finding hardware I/O address
2. Read/Write through driver. In c# Use Open Serial Port. The driver gets the hardware I/O
3. Read/Write through an application. The application does 1 and/or 2 above.

You have a working application (number 3) and I do not know if it is using method 1 or 2.

With the card reader I'm trying to make your programming as simple as possible. The easiest method is 3 if you have an API. Next easiest is method 2 which you should be able to use if you installed the vendor driver. You should see device in device manager.

To unlock the card (encryption) you also need to install the certificate than came with card. The file explorer should be able to read/write card.
