with people worried about hardware wallet tampering, you can open your @Keycard_ with this step-by-step guide to inspect the components yourself - attached below
if there’s an extra component inside your hardware wallet, what reference do you have to spot it?
with Keycard Shell, you have a published reference for what should be inside
Firmware. Circuit schematics. PCB layouts. Component lists. Case designs.
here’s the hardware behind it:
• main board with STM32H573 (ARM Cortex-M33) microcontroller (PSA Level 3 / SESIP3 certified)
• 240×320 TFT IPS color LCD screen
• heavy-duty silicone keypad (numeric + OK/C)
• ISO 7816 smartcard reader module (contact only)
• CMOS global-shutter camera for QR codes
• replaceable Nokia BL-4C 800 mAh battery
• clear ABS case, with public 3D design files so you can print your own
the clear case lets you see parts of the board without taking the device apart
the back cover slides off without tools to access and replace the battery

Panel alert: What Cypherpunks Can Learn From GenZ?
How young people already practice informal privacy with burner accounts, close-friends lists, pseudonymous online identities, even without the vocabulary of “privacy tech.”
What cypherpunk builders can learn from how teens already protect themselves socially, and what tools would actually meet them where they are.

ambire + keycard are a great combo

Transparency beats trust. So we made Shell hardware easy to verify.
Here are videos and pictures to help you check the integrity of your Shell:

that's the beauty of open source development
Work that came from this prototype was merged upstream to @Keycard_ !!!🥳 github.com/keycard-tech/keyc…
we have a lot of differences
Tangem runs through the Tangem app, so your recovery depends on Tangem’s card ecosystem existence, if you lose all your cards your funds are gone - there’s no universal standard to fall back on
With Keycard your backup is a standard BIP39/SLIP39 recovery phrase - any wallet in the world can restore it, no proprietary app and is independent of our existence
plus we have a Shell for trusted display, you don’t always have to rely on your phone’s screen to know what you’re signing
imo Tangem optimises for people who’d lose a seed phrase. Keycard optimises for people who want standards and independence
