After skimmers were found at two gas stations in Hudson and one in North Hudson, the police departments have advice on how to avoid them.
Skimmers are used to collect information from credit and debit cards, sometimes creating cloned cards that can be used or sold on the dark web, Hudson Police Detective Pearson said.
These skimmers are normally about a foot in length, Pearson explained. One end connects to the internal card reader and the other end connects to the portion inside the machine that collects credit card information. Skimmers on ATMs can also connect to the keypad, in order to record pin numbers.
