ABOUT OURINTEGRATED RFID BLOCKING TECHNOLOGY: We want to make sure your identity is safe when out traveling, shopping & getting things done. This is why we've equipped our leather minimalist wallet with a protective layer that blocks 13-14Mhz electronic signals trying to retrieve your personal information. Thieves use these signaling devices to steal credit card numbers, expiration dates, identifiable details & so much more. Using an RFID blocking wallet like ours is the easiest & most affordable way to ensure your pertinent info is safe & secure. Though it effectively guards against common radio frequencies, our id window minimalist wallet doesn't have the ability to block 125 KHz signals such as those for hotel room keys & access cards. No other front pocket slim wallet covers all the bases like this one.
