Madam Chair, one of the main methodologies of obtaining information from bank machines is something called skimming. There could be a false insert placed into the bank machine where people actually key their numbers into what they think is a legitimate machine and it processes it but the data is being captured.
You'll notice on bank machines today, there's a little bit of a shield over the PIN pad to protect your PIN, your personal identification number. People in the past have installed cameras in the vestibules where the bank machines are so they could watch and record you punching in your PIN and the magnetic strip at the same time would be compromised by the skimming machine.
At the end of the day or in the morning before the bank would open, the criminals would go back, remove the insert and then download all the information in the video, getting multiple PINs and multiple magnetic strips, and then they will upload them onto other ones. They compromise multiple cards, create them in a factory-type setting, and then attempt to bleed as many accounts as they can.
