… with a high-tech twist. Via BBC, in the port city of Volos, you obtain the “currency,” a set of online accounts called TEM, by offering goods or services for barter. You obtain others’ goods and services by debiting your TEM account and crediting theirs. It is not intended as a replacement for the Euro, but many businesses and individuals offer products and accept TEM in payment. It’s effectively a small currency system completely independent from the Euro, and it enables people Euro-impoverished by government austerity to get on with their daily lives by trading with each other.
