Protects your RFID enabled credit cards, passport, driving license, office door passes etc from RFID skimming (electronic pick-pocketing).


You no longer need to wrap your credit card in foil. Just keep VAULTCARD together with your cards in your wallet to ensure unmatched RFID security.


The card is only 1.1 mm thick and will perfectly fit in your wallet or cardholder.

VAULTCARD RFID Blocking Card shield, most advanced protection for your wallet or card holder
Patented Technology

The card uses sophisticated electromagnetic jamming technology frequently used in military applications.

No battery

The card lasts forever. The card has an extremely efficient energy harnessing technology which allows it to be powered by energy from the RFID scanner.

Auto-Adjust Power

VAULTCARD automatically adjusts the power of its jamming signal to ensure your RFID enabled cards, passport etc. remain protected even against very powerful RFID skimming systems.



As consumers have become increasingly aware of RFID fraud, a flood of products has appeared to address these concerns. All the current products are based on the same principle of shielding the RFID card from electromagnetic waves using metal foils and materials. However, in practice, this approach is susceptible to flaws.

This is due to the way that electromagnetic waves propagate through space.

To ensure full protection, your cards need to be fully wrapped in metal foil with no gaps or spaces. This is almost impossible to achieve. A typical wallet with metal shielding can only protect against low-power reading devices, and only at certain angles.



RFID enabled cards offer remarkable convenience and save a lot of time for both consumers and businesses. Governments pounced on this technology and introduced RFID technology in passports, IDs, driving licenses, etc.

Most offices use RFID building access cards nowadays. As RFID technology has become more common around the globe, significant security concerns have also emerged.

Criminals can easily acquire equipment that can access the data stored on your cards or passports from up to several meters.

With this data, they can replicate your credit card, steal your identity or get access to your building.



During a typical RFID card payment the card reader constantly transmits electromagnetic pulses (Step 1).

When a RFID enabled card is in range of the card reader it receives electromagnetic waves with its antenna and converts them to electric currents (Step 2).

The microprocessor generates a coded message with the payment or identity data (Step 3).

which is then transmitted back to the card reader using the card’s internal antenna (Step 4).



VAULTCARD switches on automatically when it senses the electromagnetic wave emitted by an RFID scanner.

It responds to a signal strength a hundred times smaller than what your RFID enabled cards need. Vaultcard then creates a sophisticated electromagnetic jamming signal that blocks RFID readers.

This principle is frequently used in military jamming systems.

The stronger the signal of the scanner, the stronger the jam signal that Vaultcard will generate. This way your credit cards, passports, etc. remain protected from even the most powerful scanning devices.



Place your VAULTCARD in the middle of your wallet. All RFID enabled cards will be protected within 4 cm (1.6 inches) of VAULTCARD. Cards can be on either side of VAULTCARD, so your wallet can be up to 8 cm (3.2 inches) thick, which should be more than enough.

Now you can use your credit card normally. Just make sure to hold it at least 20 cm (8 inches) away from the VAULTCARD.


With contactless card payments growing in popularity, our personal data is increasingly at risk of interception by fraudsters. The RFID technology that allows them to function is not entirely secure and can be accessed by scanning devices that are freely available online. VAULTCARD™ is a credit-card-sized tool, which can be placed inside a wallet to block electromagnetic signals – guaranteeing protection against RFID theft, while still enabling the use of contactless payments.

VAULTCARD's patented RFID protection technology is unique to contactless card safety devices and is based on highly sophisticated jamming signals frequently used by the military. We have invested a great deal of time in research and development to create our final VAULTCARD™ prototype. Its unmatched protection utilizes an extremely efficient design, which emits a complex jamming signal that completely shuts out any RFID communication.


In addition to a highly sophisticated jamming signal, VAULTCARD™ is extremely efficient in harnessing electromagnetic energy emitted by RFID scanners. This allows VAULTCARD™ to retransmit 1,000 times more power than RFID payment cards.  The table below represents laboratory test results of VAULTCARD™ and a typical RFID enabled credit card. For test purposes we used a popular 250mW NFC scanner with an electric E-field shielded antenna (so the scanner only working mainly with the magnetic H-field of Electromagnetic Field, diameter of magnetic antenna 45 mm).

Due to the form factor of an antenna embedded in the credit card, RFID scanner and VAULTCARD™, the most critical area is the so-called near field zone (within 0–3 inches between credit card and RFID reader). Our team has focused on ensuring that VAULTCARD™ can be used not only against far-field scanning devices, but is also extremely effective in the near field.


Another feature of VAULTCARD™ is that its emitted power is directly proportionate to the power of the scanning device, unlike RFID enabled credit cards. This guarantees that VAULTCARD™ stays extremely effective even against high-powered skimming devices.
