Also take into consideration the fact that these malefactors can also get hold of the data present in the microchip identity documents, so a shielded wallet with anti-RFID protection will also protect you from theft of these.
It must be said that modern cards have a series of protections and above all the warning service in the event of unauthorized payments, as well as the possibility of being able to check the movements made at any time.
