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.
