The zero currency bill of your country is a tool to help you achieve the goal of zero bribery and corruption. The note is a way for any citizen to say NO to bribery and corruption without the fear of facing an encounter with persons in authority. It lends voice to the voiceless, adding that the individual handing out the Zero Currency Bill is not a lone individual, but is part of a larger network of like minded citizens opposing bribe/corruption.
If you are confronted by someone asking you for a bribe, just print your country's zero currency bill, keep it handy and hand it to them. This will let the corrupt official or bribe-seeking person know that you refuse to subscribe to their acts of corruption and your refusal is certain to imply a follow up action with anti-corruption enforcement agencies of the local jurisdiction. In turn the corrupt person is bound to oblige to your democratic right in the form of an approval, certificate or a license.
