This documentation covers the '|release|' version of nfcpy. There are also other versions.
The nfcpy module implements NFC Forum specifications for
wireless short-range data exchange with NFC devices and tags. It is
written in Python and aims to provide an easy-to-use yet powerful
framework for applications integrating NFC. The source code is
licensed under the EUPL and hosted at GitHub. The latest release
version can be installed from PyPI with pip install -U nfcpy.

def beam(llc):
snep_client = nfc.snep.SnepClient(llc)
snep_client.put_records([ndef.UriRecord('http://nfcpy.org')])
def connected(llc):
Thread(target=beam, args=(llc,)).start()
return True
with nfc.ContactlessFrontend('usb') as clf:
clf.connect(llcp={'on-connect': connected})
