Apex Flex - the ultimate security solution

The Apex Flex is our ultimate subdermal security key for digital identity, cryptography, and blockchain applications!

The Apex Flex is a patent-pending subdermal security key from VivoKey Technologies that enables a constantly available, fully autonomous separation of cryptographic functions from vulnerable general-purpose computing platforms such as your smartphone or computer. The ability to carry your OTP authenticator, PGP, and other cryptographic keys with you and perform cryptographic functions "in vivo" (generating OTP codes, encrypting and decrypting data, etc.) without private keys ever being exposed to the NFC interface you interact with represents a major advancement in personal digital identity and data security.

Your Apex Flex kit includes the following items.

• Apex Flex implant, sealed in a Tyvek pouch and gas plasma sterilized
• Special 4G (5 mm) Flex installation needle (unlubricated)
• 1 packet of sterile surgical needle lubricant

Manufacturing of the Apex Flex

The Apex Flex implant is manufactured in small production batches in the USA. After inspection and cleaning, it is sealed in a Tyvek sterilization pouch with a process indicator and then sterilized using gas plasma. A batch label with processing and product details is applied to the pouch, and the pouch is sealed inside a polymer bag to protect the sterilization pouch from contamination during storage and shipping.

Using the Apex Flex

Once you have installed your Apex Flex, take your smartphone. Install the VivoKey Apex Manager app and the Fidesmo app. Open the Fidesmo app, scan your Apex, and receive a list of supported applets that you can deploy to your Apex. Applets are available from multiple providers on the Fidesmo platform, and VivoKey also publishes its own applets such as the OTP applet and the NFC sharing applet.

VivoKey Applets

VivoKey has developed a range of applets that run on your Apex Flex! Here are some links;

• OTP Authenticator - This One Time Password applet replaces many two-factor authenticator applications that store and generate OTP codes on the phone itself, making them vulnerable to loss, theft, etc. With the OTP applet running on your Apex, you only need to install the Apex Manager on ANY smartphone to generate and display your OTP authenticator codes without risking your security.

• Tesla Keycard - After installation, you can register your Apex as a keycard with your Tesla 3, Y, X*, S* and use it to unlock and drive your vehicle. *Only for Model X and S manufactured in 2021 or later.

• NFC Share - you can easily share data with others by tapping a smartphone to your Apex! For example, you can share URLs, digital vCard business cards, or even binary or raw text data. Available data sizes range from 1kB to 32kB!

Other applets such as U2F, FIDO2, and PGP are also available! View the full list at vivokey.com/apex.

ATTENTION - Fidesmo Pay is not supported for Apex Flex or any other implants. We recommend the NxtPay-Infinity.

Installation notes for professionals

The Apex Flex is approximately 7.5 mm wide and 28 mm long, with an average thickness of 0.4 mm. Installation should always be performed by a professional.

• Do not install it beneath a gripping surface (e.g., no installation in the palm of the hand).

• Do not place it over or parallel to joints (Flex devices are only "semi-flexible")

Important information about Flex products in general

• The biopolymer is tested and certified according to ISO 10993 and USP Class IV. However, the final product has not been tested after processing, meaning material changes during processing could potentially make the final product unsafe in some way.

• There is no "preferred" location for installing a Flex device. Customers are free to install a Flex device anywhere on the body, as long as it is placed in the fascial layer between the dermis and muscle tissue and not in a flexing area or beneath a gripping surface. However, the side or edge of the hand is not recommended, as tension is greatest in that area. Work together with the installer to determine the best and safest location for your Flex device.
