Essential Stamping Tools and Setup
- Automatic or Manual Punch: For creating indentations.
- Sharpie Fine Point Marker (not Ultra Fine): For inking.
- Sturdy Surface: No anvil needed—use a solid table to maximize punch impact.
- Optional Aids: Magnifying visor, reading glasses, earplugs for comfort.
Step-by-Step SeedQR Stamping Process
1. Prepare Your Reference
Reference punch marks directly from your SeedSigner, Hardware Wallet, or existing QR Backup.
For added convenience (optional):
- Create a paper SeedQR code. Verify by scanning SeedQR.
- Transcribe from PaperQR to ColdQR. Destroy Paper QR after Stamping.
2. Get Comfortable and Focused
- Adopt an ergonomic position.
- Use ear protection to reduce noise fatigue.
- Take breaks if distracted or tired—accuracy is key for Bitcoin cold storage.
3. Punch the Dots
This is a two-step process:
- Use guide marks (tiny pre-etched indentations) for precise alignment.
- Slide the punch tip until it catches in the desired spot.
- Work in grid sections to avoid errors.
Pro Tip: The plate’s thickness eliminates the need for backing. A firm surface ensures clean, deep punches.Mistake? No Problem! QR error correction forgives small errors. Pause, reset, and continue.4. Ink the Punches for Optimal Scanability
- Use a Sharpie Fine Point Marker.
- Drop the tip into each indentation and wiggle gently for full coverage.
- Magnification helps here too.
Inking Error? Wipe away with rubbing alcohol and a Q-tip or paper towel.
5. Verify and Finalize
- Scan with your hardware wallet or signer.
- Test in various lighting—indirect or dim light often works best.
- Avoid strong overhead lightning as it makes scanning harder
- Optionally, etch your key’s 8-digit hex fingerprint on the back for easy identification.
Common SeedQR Stamping Mistakes to Avoid
- Rushing grids: Stick to small sections.
- Weak surface: Absorbs force and ruins punches.
- Poor inking: Leads to scan failures—ensure full darkening.
