Vaultcard

The VAULTCARD™ is your pocket-sized protection against RFID fraud, shielding credit and debit cards to keep personal data safe. The same size as a standard credit card, this little gadget protects your RFID enabled cards, passport, driver's license, office door passes, and more from RFID skimming. The card is only 1.1mm thick and will perfectly fit in your wallet, while staying relentlessly effective against all modern RFID/NFC systems operating at 13.56MHz.

The card uses sophisticated electromagnetic jamming technology frequently used in military applications, and it lasts forever. It even has an extremely efficient energy-harnessing technology which allows it to be powered by energy from an RFID scanner - meaning that it only powers on in the presence of danger, and automatically adjusts its output based on the strength of the detected scan. This means that VAULTCARD™ is specifically powered by the very things its meant to stop, and only every uses the exact amount of power that it needs to keep your cards protected.
