September 8th, 2014 (InsideCostaRica.com) A Czech man and a Romanian man were arrested in raids last Thursday in San Pedro on suspicion of defrauding at least 250 ATM users out of at least ¢110 million (~$207,000) through the use of ATM “skimming” devices.
The Criminal Court of Pavas imposed three months of preventive detention on the men on Friday.
Authorities were able to seize skimming devices and cloned credit and debit cards in the raids.
While not a new problem in Costa Rica, credit and debit card fraud through the use of electronic devices called ‘skimmers’ is becoming ever more common as the skimming devices become ever easier to obtain.
The devices do their work after a criminal inserts the thin plastic device into an ATM machine’s card reader. The device than reads and stores every ATM users’ card information the moment they insert the card into the machine. The criminal returns later in the day and retrieves the device, which may by then have the full data of hundreds of cards stored on it. That information is later used to create clones of the users’ cards, or for online purchases.
Most of the devices allow the ATM machine to function like normal, and as a result many users have no idea that their card information has just been stolen.
Inside Costa Rica has warned readers of the scam on several occasions and has received reports from several victims of the scam over the last year.
One reader reported to Inside Costa Rica in July that criminals nabbed $600 from her account and $2,000 from two other friends’ accounts using ATM skimming devices, one of which was apparently installed at the Banco Costa Rica branch location in Grecia.
Francisco Segura of the Judicial Investigation Organization (OIJ) said last year that many cardholders have no idea that they have become victims, and that many times it is instead the banks that alert judicial authorities to possible fraud.
In an operation last year, the OIJ conducted 13 raids in various locations, collecting evidence such as payment receipts, skimming devices, and computers.
The skimmers are also sometimes placed in the credit card terminals at retail establishments, restaurants, and other places that accept credit cards.
The skimming devices used by criminals can be found for sale on certain web sites in Costa Rica, sometimes carrying a price tag of nearly 1 million colones ($2,000).
To avoid becoming the victim of these fraudsters, it is suggested to check closely the area on ATM machines where you insert your card for anything that may look like a hidden our out of place device.
