Dangerous Things
Skip to main content
  • The Indiegogo campaign for the xNT--the first NFC implant--is considered the genesis of Dangerous Things.

  • The original 'magic' implant. It used the LF emulation powerhouse that is the Atmel t5577.

  • A TiN coated 3x1mm fingermagnet was the first of DT's biomagnet offerings.

  • The world's first injectable biomagnet, an axially magnetized c'ylinder.

  • The first biopolymer implant. A high performance NTAG216.

  • 2016 - UKI

    First gen smart card implant based on NXP's p40. Two made and installed.

  • 2017 - xM1

    MIFARE Classic 1k. The original HF access control implant was a legitmate NXP chip.

  • 2018/7 - xBT

    Injectable temperature-sensing transponder. Compatible with animal-grade RFID readers at 134 kHz.

  • 07/2018 - flexDF

    DESFire EV1 NFC chip in flex form.

  • 2018 - xM1+

    Magic MIFARE Classic 1k gen1a to fully exploit legacy support of the broken MFC. To complicate things, the '+' was dropped when we switched fully to magic MIFARE chips for MFC.

  • 2018 - Flex One Beta

    Second gen smart card implant based on NXP's p60.

  • 2018 - Spark

    First generation VivoKey Spark. ISO15693.

  • 2019/2 - xHT

    HITAG S2048 chip in glass, aimed at legacy HITAG-based access control systems.

  • The wildly popular dual frequency NExT has a NTAG216 and t5577 in 2mm bioglass.

  • 2019/8 - xLED

    Implantable RF field detector. Embedded LEDs light when the chip enters an active reader field, useful for finding alignment and confirming reader range. HF and LF variants.

  • Tritium vial in Dangerous Things bioglass. The response to the Firefly implants upon observing manufacturing issues.

  • 2019/11 - Spark 2

    The second generation of the Spark implants. This one based on ISO14443a.

  • 2020/1 - xSIID

    The first blinky implant! Electronics designed by Dsruptive, encapsulation by Dangerous Things.

  • 2020/3 - xSLX

    The second ISO15693 implant. This one a SLIX2.

  • 2020/4 - flexEM

    This t5577 brought spectacular range and durability.

  • More magic MIFARE Classic goodness with the coupling performance of a flex antenna

  • What if you could have a NExT with monstrous range? And blink?

  • A MIFARE Classic 1k on a flexEM antenna — and optionally with an LED. Discontinued due to material waste and antenna enamel degradation over time.

  • 2020/8 - Titan Biomagnet Campaign

    The titanium-encapsulated biomagnet, brought to market across three crowdfunding campaigns. Production ceased — small, high-precision parts at the volumes needed simply weren't cost-effective.

  • 2020/10 - Custom 4g Needle

    With this new needle and new antenna design, suddently flex installation could be quick and simple.

  • 2020/12 - flexMN

    A limited-batch t5577 in flex form, with optional LED nails. Always meant as a short run — high per-chip cost and low demand made longer production impractical.

  • 2021/2 - xG3 v2

    Refresh of the xG3 axially-magnetized injectable biomagnet.

  • 2021/8 - flexClass

    HID iCLASS in flex form, with personalization mode enabled. The first flex implant aimed at iCLASS-based access systems.

  • 2022/7 - Apex Flex

    VivoKey Apex JavaCard implant in flex form. A platform for user-installable applets — FIDO, OTP, payment cards — running on an NXP secure element. Released to the public after DT Club pre-order fulfillment.

  • 2025/4 - NExT v2

    Updated NExT with the same NTAG216 + t5577 dual-frequency design, now available in multiple shell colors.

  • 2025/6 - Glow Powder

    Strontium aluminate glow powder in green, aqua, and blue at 50 micron — the pigmented bioresin material used for Glow Heart and similar glowing implants.

  • 2025/6 - Memora

    A bioresin memorial implant — cremated remains of a loved one mixed with optional glow powder, encapsulated and pre-loaded in an injector. ~3.1mm diameter. Carries no chip.

  • 2025/8 - m-Series Biomagnets

    First in the new 'm-Series' magnet line — non-injectable, encapsulated in DT's resin process. Rolled out across multiple geometries through Aug–Oct 2025 (M0426, M08s, M0422a, M1148a, M0490a, M04280bar, M1448a).
