Skimmers on ATMs are not only a problem for travelers — they are a problem for everyone. When a skimming device is attached to a cash machine, it secretly notes the credit or debit card information, allowing thieves access to an individual’s accounts.
In some places, scammers will place a sticky or plastic slip inside the machine, causing the user’s card to get stuck. This is the moment a friendly stranger shows up and helps by suggesting the user call the “bank” (the number, of course, is fake) and give out their PIN.
