A five-member gang indulging in hi-tech financial frauds through cloning of debit and credit card was nabbed by the police here.
According to police, the gang, led by a management graduate Mr Kamal Kumar lured people by a free-mobile re-charge scheme for Rs 250, by accepting Rs 50 through debit cards.
The encrypted data was thus captured from about 500 customers at the Inorbit and City Centre malls.
Huge data was also collected by the accused though a petro card scheme in Ranchi, Bihar.
Mr Sura alias Kronik of Canada helped the accused in decryption of data online, which was cloned on blank plastic cards using magnetic card-writer.
They also received technical help from Mr Alex Rosenberg of Russia and procured four personal identification number (PIN) pad skimmer machines.
â€œThe cards were used to withdraw money from different ATMs located in various cities which ran into a few crores,â€ the police said in a release.
The ATMs of Corporation Bank and Canara Bank were targeted by the accused because of their familiarity with the technical details of ATMs models used by these banks.
They were also involved in misuse of data obtained from cards of the Canadians.
The gang had also set up a card skimming lab at Motinagar, which was seized by the police.
The electronic method of capturing one’s personal financial data for illegal purposes during legitimate financial transactions is referred to as skimming.
The further investigation in the case is on, police said.
