Two men accused of attaching a card-skimming device on an ATM in Wai­kiki to steal credit and debit card information pleaded guilty in state court Thursday to identity theft charges.

Armen Apoyan and Argishti Kha­cha­tur­yan face mandatory 20-year prison terms at sentencing in March.

The state says the two men traveled to Hono­lulu from Los Angeles in February 2013 and installed an "overlay skimming device" on a Central Pacific Bank ATM at the Wai­kiki Shopping Plaza.

An overlay device attaches to the outside of the ATM at the card-reader slot and records data from credit and debit cards customers use to withdraw money from an ATM without disrupting the transaction.

The state says the men left the skimmer on the shopping plaza ATM for three days, then used the data it captured to make counterfeit debit cards. They used the counterfeit cards to withdraw money from victims’ accounts at an ATM at The Modern Hono­lulu hotel in Wai­kiki and at other ATMs in Hono­lulu. They then returned to Cali­for­nia where they continued to use the counterfeit cards.

Authorities arrested Kha­cha­tur­yan in Los Angeles in September 2013 and Apo­yan in Seattle in March.

In 2013 two other Cali­for­nia men who had installed card skimming devices inside self-service gasoline pumps on Oahu were sentenced in state court to 20-year prison terms for identity theft.
