A security device for mailing credit cards or the like, particularly for credit cards that do not require direct contact with payment terminals, the security device comprising a sheet-like element (2) that has a central region (3) that is adapted to cover a credit card (4) or the like and peripheral portions (5) that extend around the central region (3), the peripheral portions (5) having, on the face of the sheet-like element (2) that is intended to be directed toward the credit card (4), an adhesive layer (6) that can engage a backing sheet (7) so as to define, between the backing sheet (7) and the sheet-like element (2), a compartment (14) that is adapted to accommodate the credit card (4), the sheet-like element (2) being provided with breach-prevention means (9, 10, 13), which are adapted to render evident a fraudulent attempt to separate the sheet-like element (2) from the backing sheet (7), and with a protective element (15) that is adapted to prevent the correct transmission of electromagnetic waves of at least one preset frequency through the sheet-like element (2).
