NAME

7       based on libnfc

SYNOPSIS

10       nfc-anticol
11

DESCRIPTION

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