A body scanner that would supposedly allow people to make 3D-printed models of themselves or their pets was one of many scams that saw a Sydney man illegally pocket almost NZ$6.2m, authorities allege.
NSW Police say Daniel Kive Albert, who was extradited from New Zealand this week, fleeced dozens of people in nine countries out of NZ$6.5 million over five years.
The elaborate schemes involved registered companies including some named First Aerial, Switched on Social and 3D selfie printer franchise Identical You.
Police allege the scams affected people in Australia, New Zealand, the United States, Canada, Ireland, Lebanon, Qatar, Singapore and South Africa.
The 51-year-old is alleged to have defrauded one man of NZ$685,000 in 2012 with a fraudulent franchise venture called Glamour Nail.
An archived web page for the nail business indicates it would have offered small kiosks capable of painting more than 1000 designs onto fingernails.
Albert appeared via video link in Central Local Court on Friday on 35 fraud charges allegedly committed between 2012 and 2016.
Lawyer Greg Goold told the court his client had "voluntarily" handed himself to New Zealand police before his extradition from Auckland on Thursday.
Court documents indicate a warrant was issued for his arrest in March when the charges were filed in a Sydney court.
Mr Goold didn't enter a plea in court on behalf of his client but later told reporters he expected Albert would plead not guilty.
"This may well be a civil dispute instead of a criminal dispute," Mr Goold said.
"It depends on whether the products police say existed did exist."
Albert, whose address is listed as a luxury apartment in Potts Point, is expected to make a bail application on November 24.
An accomplice - a 48-year-old Woollahra woman - has also been charged with 35 counts of fraud.
