NAME
nfc-poll - poll first available NFC target
SYNOPSIS
nfc-poll
DESCRIPTION
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.
OPTIONS
-v Tells nfc-poll to be verbose and display detailed information about the targets
shown. This includes SAK decoding and fingerprinting is available.
IMPORTANT
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.
