.SH DESCRIPTION

|
|
.B 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.
