ROCHESTER, N.Y. (AP) — Democratic Sen. Chuck Schumer says recent credit card skimming incidents in upstate New York show the need to step up federal investigations of the issue.

Schumer is urging the Secret Service to devote more agents and resources to counter skimming crimes.

A credit card skimmer is a device that skims the magnetic strips on cards swiped at ATMs or gas stations. The device allows thieves to steal credit and debit card numbers.

Schumer says in Livingston County alone, more than 20 cases of credit card fraud were reported in the past seven weeks that are believed to be related to skimmers at area gas stations.

On Monday, state police said two men from Florida have been arrested for skimming devices on gas pumps in the town of Amsterdam.
