Devices for stealing card numbers are increasingly difficult to detect. To top it off, some of them work in conjunction with a small camera activated by a smartphone battery and mounted on a small structure that is hidden above the keyboard. While the reader copies our card number, the camera records the pin we mark. Both data are sent directly to a nearby smartphone.
Other card-copy readers protrude a bit from the slot, but are made of clear plastic so that they appear to be part of the cashier. For now, the only method to prevent our card from being copied (apart from not using ATMs) is to carefully check the machine in which we are going to carry out an operation and, if there is something that is strange, to desist from doing it.
