Bartercard

A barter trading exchange founded in Australia in 1991, which now operates in a number of countries including NZ. Member businesses can exchange goods and services with other member businesses without using cash/cash equivalents, or having to engage in the direct two-way swap of goods and/or services. Members get credits which they can earn by providing goods/services and spend.

The hotel industry utilise Bartercard to fill unsold rooms, restaurants use Bartercard to fill tables, the wine industry uses Bartercard to increase their marketing and distribution, and trades people and professionals use Bartercard to fill their work weeks and gain new business. The Bartercard network is focused on connecting business people with each other and holds over 500 networking events per year. source

When you spend cash there is no guarantee of the return. With the Trade Dollar you know that each time you spend, it will come back to you in the form of new business from another Bartercard member.
Bartercard members are motivated to utilise your goods and services because they are paying with their Gross Profit Margin just like you, saving them cash every time they spend. source

1 bartercard dollar =  1NZD.  Essentially it seems very commercialised and still focused on gaining money which is not exactly what we're focusing on in this paper but I thought I'd add it anyway.



Another interesting thing: Silent Trade, a system generally between groups who don't speak the same language. More of a historical thing than something that's still in use.
