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.
