nfc-poll  is  a  utility for polling any available target (tags but also NFCIP targets) using ISO14443-A,
       FeliCa, Jewel and ISO14443-B modulations.

       This tool uses hardware polling feature if available (ie. PN532) or switch back to software  polling,  it
       will display available information retrieved from the tag.

       There are some well-know limits with this example:
        - Even with NDO_AUTO_14443_4A enabled (default), nfc-poll can miss ATS. That due to the  way  the  PN532
       use  to  poll  for  ISO14443 type A, it will attempt to find ISO14443-4-only targets, then ISO14443-3. If
       your ISO14443-4 target is present when PN532 looks for ISO14443-4-only, ATS will  be  retrieved.  But  if
       your target enter the field during ISO14443-3, RATS will not be sent and ATS not retrieved.
        -  nfc-poll  can  show  up only one card while two are in field. That's due, again, to the way the PN532
       poll for targets. It will stop polling when one modulation got a result, so if you have, for example, one
       ISO14443-3 (eg. Mifare Ultralight) and one ISO14443-4 (eg. Mifare DESFire), it will probably return  only
       the ISO14443-4.
