Read data from USB RFID reader using Python

I'm trying to read data from USB RFID reader using Python script. The data was write into a RFID sticker using NFC tool on my phone. So when I scan the RFID sticker at the RFID reader, Python script should display the data that I write into the RFID sticker.

For example, I write a string into RFID sticker with "Hello World".

I want it to display the string.

But this does not work. I think it doesn't work because the script used for different reader model. I tried to find the RFID reader info on my Linux by using these command.

But this command `sudo tree /dev/input` do not showing any device related to my RFID reader.

Hardware:

 - USB RFID reader EM4100
 - RFID sticker NXP MIFARE Ultralight (Ultralight C)

From my understanding, USB should be used as serial library in Python, but the reader act as a HID device. So I tried installing Python library using this command.

> sudo pip install hid

Anyone know how to make the Python script work or any guide that might related?

Thanks.
