The Secure Badgeholder Duolite is designed to hold and shield two cards. Our Easy-Slide technology allows the card to be read by simply sliding the front card partially out the top or sliding it sideways on the back of the duolite. Slide it back into place and the card is shielded once again! Our Secure Badge holders are made of extremely durable polycarbonate. Used by U.S. Government agencies like FBI, FAA, Secret Service, and DHS/TSA. The state of the art unique two-sided design keeps the card locked-in to prevent loss, yet allows easy access to remove the card when necessary. Shields two ISO7810 ID-1 form factor (credit card size) TWIC, PIV, CAC, or other identification card. The perfect choice for TWIC, HSPD-12 PIV, CAC, HID iClass, LincPass and other RFID enabled cards. Don't risk identity theft, invasion of privacy, tracking, or even card cloning. Always keep your contactless cards in a shielded Secure Badge Holder. Identity Stronghold started the RFID protection industry in 2006. We continue to lead this industry by creatively applying shielding technology to a variety of products that block radio waves and thereby prevent thieves from remotely accessing your private information (including your complete credit and debit account numbers). Beware of imitations that aren't made by Identity Stronghold. We have tested many of those knock-offs in-house, including some of those hard metal wallets. Many do not shield effectively. In fact, some knock-offs actually include documentation admitting they are not 100% effective. You can be sure you are protected when you use Identity Stronghold RFID blocking products. This Badgeholder will not protect 125Khz Access Cards. To protect cards with that frequency, make sure to search for our BloxProx Duolite!
