The Cardprotector is the core of the Secrid product line. The aluminium Cardprotector protects your most important cards; both against bending and breaking and against your RFID cards being scanned if you don't want them to be (such as the transportation pass; ID card; the latest credit cards and business cards).

Some cards have thickened letters; this is called embossing. You can store up to six cards in the Cardprotector; including one with embossing. Or up to five cards; three of which with embossing. The Secrid Cardprotector is only 8 mm thick and has won a Red Dot Design Award.
