COLDCARD Mk5 adds mechanical keyboard, Gorilla Glass, full air-gapping for Bitcoin security

Coinkite’s latest COLDCARD puts a mechanical keyboard on a Bitcoin wallet for the same reason custom builders obsess over a good switch feel: when every keypress matters, confidence becomes part of the spec. The Mk5 pairs a redesigned tactile keypad with a 1.54-inch display protected by Gorilla Glass, turning the company’s compact hardware wallet into something that looks and feels more like serious-use gear than a throwaway accessory.

The security story is still the center of the device. Coinkite says the Mk5 uses dual secure elements, stays fully air-gapped, and signs transactions through microSD or QR code instead of a live USB data connection. It also adds NFC for tap-to-sign and Push TX, uses USB-C for power and connectivity, and keeps the firmware open source so users can build and verify it themselves. Coinkite says the Mk5 remains backward compatible with earlier COLDCARD devices, which matters for users who have already built workflows around the brand’s offline model.

For the keyboard community, the interesting move is not that a wallet has buttons. It is that Coinkite leaned into a more precise, tactile input experience at all. Earlier COLDCARD models began with a touch keypad, and the Mk5 continues that evolution toward a sturdier physical interface. In a device built to handle passphrases, PINs, and transaction confirmation without ever feeling fragile, the switch-like character of the keypad becomes part of the trust story. The tactile front end matches the wallet’s deeper promise: fewer surprises, clearer feedback, and a better chance of entering sensitive data correctly on the first try.

Coinkite positions the Mk5 as a smaller, more affordable option beside the COLDCARD Q, which adds a full QWERTY keyboard, QR scanner, battery support, and every Mk5 feature. That makes the Mk5 the more compact choice, while the Q is the flagship for users who want a fuller input surface. Coinkite’s store listed the Mk5 at $189, with a promotional price of $169.94, and noted high demand and possible delays.

The company says COLDCARD has been made since 2017 and is designed and assembled in Canada. The Mk5 is also documented as an upgrade over the Mk4, with the bigger Gorilla Glass screen, USB-C, improved NFC, and a more refined keyboard. In a market built on caution, Coinkite is making a familiar mechanical-keyboard argument: better feel is not cosmetic, it is part of durability, reliability, and the confidence to use the hardware every day.
