Revenue authorities lose excise income wherever stamps can be copied, reused or diverted. Trace Core supplies governments and revenue authorities with track-and-trace excise stamps, specified against the threat rather than against a catalogue.
Each programme is customised for the authority that runs it. The stamp carries overt features a field inspector can check by eye and covert features that need a reader. Serialisation ties every stamp to the batch it was issued against, so volumes declared can be reconciled against volumes marked.
Systems are built to work with the regulatory infrastructure already in place, rather than requiring an authority to replace what it has.
