s are a community currency issued by the
Salt Spring Island Monetary Foundation. The currency is used by both tourists and local residents of Salt Spring Island. Modern local currencies can be classified into the following distinct types: • Transition currency based on the local currencies used by the
Transition Towns movement in the UK. They include
Brixton Pound and
Bristol Pound in the UK,
BerkShares in the USA, and
Salt Spring Dollars in Canada. Transition currencies are payment voucher-based systems that are exchangeable with the national currency. Local currencies were used in some municipalities in the Depression, such as
Vermilion, Alberta. The issuing of
scrip, sometimes in the form of stamped scrip, is the equivalent. Between 2002-2014 many experiments in local currency took this form. Such currencies aim to raise the resilience of local economies by encouraging re-localisation of buying and food production. The drive for this change has arisen from a range of community-based initiatives and social movements. The
Transition Towns movement originating in the UK since 2005 has used local currencies for re-localisation in the face of energy descent from
peak oil and
climate change. Other drives include movements against
clone town and
big-box trends. • Rewards currency based on the frequent flyer model. Consumer spends cash with participating businesses who issue rewards points in a local currency. These rewards points can be used to offset cash prices in future purchases. An example is Oakland Grown in Oakland, CA. • Mutual Credit currency based on the
mutual credit system. This can be further sub-divided into two: •
Time-based currency also known as Time Banks that use time as a measure of value. An example is Dane County Time Bank. • Trade exchanges and LETS (
local exchange trading system) that use price as a measure of value. An example of local currency implemented as a trade exchange is Bay Bucks in the Bay Area of California, USA. LETS were originally started in Vancouver, Canada, there are presently more than 30 LETS systems operating in Canada and over 400 in the United Kingdom. Australia, France, New Zealand, and Switzerland have similar systems. ==Software==
