Coinkite Coldcard is BIP39 based, meaning you can secure the secret words on paper and have many sub-accounts and unlimited independent payment addresses.

It knows how to understand transactions so you can see what you are approving.

But it's different!
NO special software required. It looks like a hard drive, so you can drag and drop files into the hard drive. NO companion “app” on your computer!

Its cheap! Simple packaging, simple design, no fancy boxes, no redundant cables.

It's ultra safe! A real crypto security chip. Your private key is stored in a dedicated security chip, not the main micro's flash.

Easy backup! MicroSD card slot for backup and data storage. This enables true offline signing by transmitting the unsigned/signed transactions over Sneakernet.

Open source software design runs on Micropython and you can modify it.

Other features:
The full-size numeric keypad allows for easy and quick PIN entry.

Larger 128x64 OLED screen.
