Whatever their age, location or occupation, Australians will be poorer if the nation does not support payment choice and retain cash, says finance expert Sarah Wells.

With 20 yearsโ€™ experience in credit, risk and debt structuring, Sarah Wells provides finance solutions targeted at executives and other professionals, and she warns a cashless society will be harmful at all levels.

Wells says the first to suffer will likely be those in more remote parts of the country, indigenous Australians, new immigrants, sex workers, the very old and the very young. Starting with children, she points out physical money is a key element in early financial education.
