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
       yourself.   The  developer  has  to rely on closed proprietary software and should hope it
       does not contain vulnerabilities during the anti-collision phase.   Performing  the  anti-
       collision  using  custom  frames  could protect against a malicious tag that, for example,
       violates the standard 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.
