Fraud with bank cards by stealing credit cards is a common case. If this is detected, you must immediately contact the operator and block the card or do it yourself through a mobile or Internet application. This is extremely important when the plastic has only a magnetic stripe. It is not possible to withdraw money without a PIN code, but it is not difficult to pay in the store. Cards with a chip or with contactless payment are more difficult to use, because for any operations you will need to enter a secret password number.
