Police have not said how many victims are involved, but officials are warning the public to remain vigilant as the investigation continues.
Police are investigating a pattern of skimming devices installed on payment machines. These devices can steal credit card information if you insert or swipe your card.
According to law enforcement, the scheme involved 25 people and four companies operating in New Jersey, Pennsylvania, New York, Connecticut, and Massachusetts.
Shown on surveillance video, the suspect approaches the register and asks the clerk for a pizza. When the worker walks away, the suspect pulls a device out of his pocket and quickly installs it on the reader.
The Kutztown Police Department is warning about a skimming device that was found at a CVS on Sunday.
At this point, police in all six townships are still trying to figure out exactly when the devices were installed, but are urging anyone who visited the stores to monitor their card activity.
