People and businesses participate by accepting Current-z notes in lieu of cash payment for goods and services. They then use the certificates to receive goods and services from other local providers. 

The certificates are created by the participants and are treated as regular currency from then on. The certificates introduce and advertise local providers. The certificates look the same on the front, except for the many different faces. On the back of each note are the business names and contact information that belong with the face.

Players use a provided graphic template to input their own picture and contact information for the back of the certificate. The certificates are the size of a debit card and are softly laminated in flexible plastic.

The faces on the Dollars are of local providers.  These notes show Robin Verson of Hill and Hollow CSA, Evelyn Yater who supplies eggs from the chickens she keeps, and Kay Williams of Otherworld Food Co-op. 

Members who buy with Otherworld Food Co-op receive a 10% volume discount on their non-sale purchases ordered from United Natural Foods, in the form of a local currency rebate. They may opt out of the program by accepting a 6 percent cash volume discount instead.

The certificates are figured at cash value, and if you place a certificate into circulation, you can think of it as an outstanding check. If someone brings it back to you, you redeem it for goods or services. Green Currents are $1, Pink are $2, Indigo $3. A $10 certificate is also valued as one hour of someone's time.
