KARACHI: Police arrested two Chinese nationals allegedly involved in ATM skimming fraud in Karachi on Wednesday, officials said.

The arrested foreigners were seen suspiciously doing rounds of ATM booths on Karachi's Abdullah Haroon Road. Local shop-keepers took hold of the two and handed them over to police.

Officials have now confirmed that the two foreigners have been involved in ATM skimming.

"We have recovered ATM skimming devices from both the suspects," confirmed SP Saddar Tauqeer Naeem.

"They had come to remove detach skimming devices from the machines," Naeem added.

What is ATM skimming?

ATM skimming is can be regarded as identity theft for debit cards. Fraudsters employ different techniques to record your PIN code for accessing the hard-earned money in your account.

In some instances, the schemers stick a fake card-reader on the ATM, while in others they place a fake keypad on the machine to get your PIN code.

Another technique employed in this crime is the use of a hidden camera, which records your PIN code and conveys it to fraudsters.

A few ATM skimmers also change the entire display of the ATM.
