Warning

WARNING This kit definitely contains dangerous things. While our chip implants have undergone several quality checks during manufacture and have been put through a battery of tests, nothing has been certified by any government regulatory agency for implantation or use inside the human body. Your personal decision to purchase and ultimately the safe use of these devices is strictly your responsibility and at your own risk.

The biopolymer is ISO 10993 and USP Class VI tested and certified, however the final product has not been tested post-processing, meaning material changes during processing could render the final product unsafe in some way.

There is no "preferred" location for installation of a flex device. Customers are free to install a flex into any area of the body their installation professional is comfortable with, as long as it is in the fascia layer between dermis and muscle tissue and not in an area of flexion or under a gripping surface. Even though we use images which suggest installation above the second metacarpal of one of the fingers, it is not an ideal location for such a device. Fingers are filled with tendons, nerve bundles, and very important things all packed into a very tight space. We urge you to think about easier locations like the back of the hand or in the arm/wrist.

flexSecure Spectrum

The flexSecure Spectrum combines the open Java Card platform with an integrated RGB LED in a 22mm disc form factor. The disc antenna provides medium range performance while the RGB LED blinks beneath your skin when scanned. Unlike the VivoKey Apex which is vendor-locked to Fidesmo, the flexSecure runs open-source applets you install yourself from the DangerousThings flexSecure applets repo.

What Can This Chip Implant Do
  • Integrated RGB LED blinks under your skin when scanned
  • FIDO2 — passwordless authentication and second factor for websites and services
  • SmartPGP — PGP encryption, signing, and authentication with on-chip key generation
  • SatoChip / Satodime / SeedKeeper — cryptocurrency hardware wallet applets
  • NDEF — store and share URLs, vCards, or other data with NFC smartphones
  • Keycard — Status/Keycard wallet integration
  • Open platform — install applets yourself, no vendor lock-in
What This Chip Implant Cannot Do
Module Contents

This is the flexSecure Spectrum module — a 22mm disc with integrated RGB LED. No installation kit, needle, or sterilization pouch is included. This option is intended for custom projects, professional installers who supply their own materials, or as a replacement module. Installation is considered advanced due to the disc form factor.

flexSecure vs Apex

flexSecure vs Apex Flex — which should I choose?

  • flexSecure: Open platform, install your own applets, no vendor lock-in. Best for developers, tinkerers, and those who want full control.
  • Apex Flex: Fidesmo vendor platform with curated applets including Tesla keycard, VivoKey OTP, and NFC Share. Best for users who want a managed experience.
