Two men have been charged over a "sophisticated" credit card skimming scheme worth $3.75 million.
NSW Police established a Strike Force in March after receiving intelligence that men from a global criminal group hailing from Romania were coming to Australia to set up an alleged card skimming scheme in Sydney.
The alleged criminal group is "well-known" to law enforcement across the world, police say.

Police allege the two men came in November last year and were committing card skimming offences and got away with $400,000.
"They returned this year, but this time we were ready for them," Detective Superintendent Gordon Arbinja, commander of the Financial Crime Squad, said.
Arbinja alleged the two men arrived in Australia on international passports with fake details.
Police carried out search warrants at two properties in Wolli Creek yesterday where detectives found an active skimming device allegedly in the process of embedding 1500 blank credit cards, which could potentially hold $3.7 million worth of funds skimmed from ATMs.
Officers also found electronic devices allegedly containing a list of thousands of bank details with matching PIN codes.
At a second property, police found $50,000 in cash, electronics, passports, designer handbags, designer shoes and designer watches.

A 40-year-old man was charged with nine offences including knowingly directing activities of a criminal group, dealing with identity info to commit indictable offence, knowingly dealing with proceeds of crime and possessing equipment to make false documents.
"We allege the younger man was a syndicate head of this particular organisation and criminal group," Arbinja said.
The 43-year-old man was charged with participating in a criminal group contributing criminal activity, dealing with identity info to commit an indictable offence, and three counts of making, and possessing equipment to make false documents.
The men were refused bail to face court later today.

Arbinja alleged the men were targeting ATMs – regardless of the bank – primarily in Sydney CBD but also in other states.
"This is an old-school type of crime," he said.
"It targets the vulnerable and elderly who rely on cash for their day-to-day activities."
He believes there are at least 3500 victims of the scheme.
"The average spend on a card that is skimmed is $2500 before the customer is alerted to the fact," he said.
"We'll speak with every bank involved and they'll directly speak with their customers."
Arbinja also alleged police are hunting for another syndicate member in NSW.
