Can't use hf mf mifare and hf mf sniff

Hello!

I am using my hf antenna to sniff card-reader communication, but not very successfully.
Here you can see hw tune command without a card and with a card:
1) # HF antenna: 16.84 V @    13.56 MHz
2) # HF antenna:  9.54 V @    13.56 MHz

If I try to use "hf mf sniff" - nothing happens
If I use "hf mf mifare" - infinite number of these messages is displayed: #db# Mifare: Can't select card

I try to read the card with a phone and gets this:
Tag type: ISO 14443-3A
NXP MIFARE Classic 1k (Classic) 1K

What am I doing wrong?

Thanks for the help!
