NAME
       nfc-anticol  -  Demonstration  of  NFC anti-collision command line tool
       based on	libnfc

SYNOPSIS
       nfc-anticol

DESCRIPTION
       nfc-anticol is an anti-collision	demonstration tool for ISO/IEC 14443-A
       tags, performed by custom constructed frames. The first frame must be a
       short frame which is only 7 bits	long.  Commercial  SDK's  often	 don't
       support	a  feature to send frames that are not a multiple of 8 bits (1
       byte) long.  This makes it impossible to	do  the	 anti-collision	 your-
       self.   The  developer  has  to rely on closed proprietary software and
       should hope it does not contain vulnerabilities during the  anti-colli-
       sion  phase.   Performing  the anti-collision using custom frames could
       protect against a malicious tag that, for example, violates  the	 stan-
       dard  by	 sending  frames  with unsupported lengths.  Note that this is
       only a demonstration tool, which	can not	handle multiple	tags  as  real
       life anti-collisions with multiple tags generate	"messy"	bits which are
       neither 0 nor 1.
