Custodians of Australia's payments networks might be wondering how the heck weird and wonderful financing ploys wander through the landscape.Hundreds of individual investors in ATMs promoted by One Cash (now in liquidation) face returns of less than one cent in the dollar from funds entrusted for the purpose of earning a yield from the fee flow of the machine at a merchant.In some cases, One Cash bought machines and paid a return to investors. In other cases, if the relevant machines were ever the property of One Cash, they have disappeared - and it may be that no ATMs were ever bought with investors' funds.In excess of one thousand investors are in this camp if Banking Day's ATM industry contacts understand the back story clearly. One key recent report by KordaMetha does not directly consider the matter but does confirm it is in discussion with Queensland Police and ASIC over "a number of possible criminal and civic breaches [of a] serious nature."Gold Coast finance broker Corr Piccone was one of the links in the One Cash fancy financing chain. Piccone played a part in sourcing investors for the One Cash scheme.Through Big Picture Alternatives, a simple web page pitched 13.5 per cent returns for VComms.When the web page was accessible, Banking Day had no trouble registering as interested, with no need to demonstrate qualifications as a well-heeled investor.A bright introductory email arrived in our inbox."Offering approximately four times bank interest rates, we have been run off our feet with enquiry from the yield hungry public," Corr Piccone wrote.His connection to the VComms financing outlined above is one alarm bell on the method by which a critical banking industry supplier found itself stuck hunting for working capital.The near-criminal state of the supply of business finance is one risk the industry must consider.
