The ONBOARDING Card is the ultimate tool for Bitcoin self-custody enthusiasts who want secure, portable seed backup without bulk. Made from high-grade 316L stainless steel, this slim 1mm plate offers triple-redundant storage options for your 12-word seed: punch a compact C12 SeedQR for fast SeedSigner scanning, use binary encoding for index-based recovery, or manually stamp each word clearly for readability. It’s ideal for introducing Bitcoin sovereignty on the go—hand it over during conversations to demonstrate real self-custody in action. While extremely lightweight and wallet-friendly, note that its 1mm thickness makes it less rugged than thicker 3mm full backups (like our SteelQR options). Fire-resistant, corrosion-resistant, and tamper-evident when properly punched/stamped.
A compact, wallet-sized 316L stainless steel plate for backing up your 12-word Bitcoin seed using three methods: C12 SeedQR, binary BIP39 indexes, and stamped human-readable words—perfect for portable self-custody and onboarding others.
Bitcoiners who want a discreet, everyday-carry seed backup for quick demos, or teaching new users about sovereignty and self-custody.
