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.
