RFID Protection Cards

This item is available for individual purchase, and can also be selected as a complimentary gift through our wallet review program.

Product Features

This security card is designed to protect the personal information stored on your credit cards and ID cards from unauthorized “skimming.”

Equipped with E-Field shielding technology, it blocks the 13.56 MHz frequency band commonly used for reading data from contactless credit cards and IC cards, helping to prevent unauthorized access from external devices.
Simply placing it inside your wallet provides an effective safeguard against invisible risks.

How to use

Insert one card into your wallet’s card pocket to activate its function.
The protective effect applies to cards placed in direct contact with this card—either in front of or behind it. For optimal performance, ensure the skimming protection card is in close contact with the cards you wish to protect.

It can also be placed between multiple contactless cards to protect more than one card at a time.
Please note that sufficient effectiveness may not be achieved if the card is not in direct contact.

Notes on Shielding Effectiveness

We conducted internal testing using a smartphone to read a My Number card (Japan’s national ID card).
The results confirmed that when more than three cards are stacked between this product, the shielding effect may not perform effectively.

When protecting multiple cards, we recommend using this product with no more than three cards in total.

Example of Use

When used with the SAKU wallet, placing this card between multiple cards enables effective protection.
It also helps reduce the risk of magnetic interference that may occur when multiple credit or cash cards are stored together.

For Use with UNO

When using this product with the UNO wallet, please store it in the card slot together with the card you wish to protect.
