RC522 Random Generator

I generate random numbers using
Write (CommandReg, GenerateRandomID)
Write (FIFOLevelReg, 0x80) // Clr FIFO
Write (CommandReg, Mem)
In the FIFO buffer, I get random numbers distributed randomly:
0008 [12E39C] 800848 [AA391F51F673] 0400B411801074C64822 [17]
0008 [F98A5B] 800848 [33080F07F32A] 0400B411801074C64822 [5F]
0008 [F1CEE3] 800848 [6859675C968A] 0400B411801074C64822 [FF]
0008 [90676F] 800848 [D82C89F9C48A] 0400B411801074C64822 [72]
0008 [F885B4] 800848 [44F3E3E7C277] 0400B411801074C64822 [2C]
0008 [1E9CD6] 800848 [498EAF9517C4] 0400B411801074C64822 [35]
Random numbers are indeed 10, as NXP writes
They are separated in square brackets.
Who can, repeat the experiment!

Why do you want to repeat the experiment?
Or what is the question?

Do you have a link to the datasheet of this chip?

Is this a random generator chip?

I would like to see the distribution of random numbers on other chips RC522.
I have a version of the chip - 0x91. I heard that there are still Chinese versions of 0x12

For work with cards Ultralight C necessary random 8 byte number.
