In the age of identity theft, thieves have found sophisticated ways of obtaining personal credit card information. Once part of a gritty subculture, gone are the days of elaborate pickpocket schemes played out on public streets.

But a duo of professional thieves decided to stick with tradition --  they were caught on camera taking the credit cards of patrons at a Pennsylvania restaurant and going on a shopping spree afterward, NBCPhiladelphia.com reported. 

The pair were seen on camera at the Nova Grill in Villanova sitting next to customers. One goes into the victim's bag, slowly taking out credit cards from a wallet. The thief then closes the bag.

No one caught on to what was happening because the thieves were assumed to be digging inside their own bags they brought into the restaurant, a restaurant worker told NBC 10. 

After getting the credit cards, the men calmly left.

"In a very meticulous fashion, he just took out her credit card, one by one, and left the wallet in the bag. Not only that, he closed the bag," said restaurant owner Costos Xinos told the station.

Authorities said the pickpockets struck the restaurant twice in May and again on July 20. One restaurant goer received an alert from her bank about the charges, NBCPhiladelphia.com reported.
