Joel David Richards, 25, from the UK, and Rudy Manoel Daas, 32, from the Netherlands, were charged with abusing digital utilities to appropriate property on November 1.
The duo used fake credit cards with stolen account information their overseas accomplices had provided to withdraw money from local ATMs.
Police in Nha Trang arrested them in December last year after being tipped off by local banks.
They admitted having stolen more than VND500 million (US$22,400) in Nha Trang. They said they also withdrew money from other places in Vietnam including Danang, Ho Chi Minh City and Hue. They used account information stolen from France, Germany and the US.
Police seized 41 ATM cards, electronic equipment used to make counterfeit cards and VND200 million (US$9,025) from their hotel rooms in Nha Trang and Danang.
