My Number Cards are equipped with an RFID (contactless communication) function.
While this is convenient, there is a risk of information being illegally read (i.e., skimming) using dedicated reading devices, even if the card is still in your wallet.
There is a possibility of information being stolen during brief encounters in crowded places like packed trains or busy streets, or while traveling abroad.

That's why, from the perspective of protecting your card, a truly reliable case is now in demand.

Q. Can I store cards other than My Number Cards?
A. You can also store IC cards, credit cards, and business cards of standard size.

Q. Is it difficult to take out the card?
A. It has a structure that allows for smooth insertion and removal, so you can use it without stress when needed.

Q. Can the IC chip be read while in the case?
A. No. This case is made of titanium material to provide radio wave shielding and skimming prevention. Therefore, please remove the card from the case when reading.

Q. Will the surface of the titanium material get scratched?
A. Titanium is a very hard material with excellent scratch resistance, but fine scratches may occur if it comes into contact with hard metals or stones. It is a material that can be appreciated as a patina over time, but if you are concerned, we recommend storing it separately.
