In some cases, this information is enough to buy an inexpensive item over the Internet, book a hotel room or make a purchase. Therefore, if possible, it is better not to transfer the card to third parties (for example, waiters in a restaurant can be offered to bring you a POS-terminal and make a payment with you, and not take your card to an unknown place). A much more complex process is scanning the magnetic tape of the card with a special device, and then making a similar card. Most often, such devices are installed by thieves in ATMs or terminals in unreliable places where there are no working video cameras. Alas, it is problematic to protect yourself from such a reading, you need to be very careful and do not withdraw money if the ATM looks unusual or suspicious.
