I am announcing
Version 10 (GPG signed zip file) of my tool with
mBTC or
mBTC or
₥ denomination support and some cleanups! (11.8 MByte).
(I got inspired
here [₥ is Unicode #20A5])
Let me shortly re-capture the benefits of this tool:
* Purpose:
- Empower EVERYONE to print your own bitcoin bills or vouchers and to allow for personal customization if required.
* Ease of Use:
- Requires no IT knowledge, no command line skills, no technical pre-requisites except Firefox
- Tested with Firefox on both Windows and Linux
- Setup procedure = extraction of a zip file - that's all !
- Start procedure = opening a local html file in Firefox - that's all !
- Well documented "user manual" and readme files
- The GUI has many "?" buttons providing detailed explanations were necessary
* Features:
- Hi resolution printout when using Firefox (but NOT with Chrome!)
- Many pre-defined templates are available as best-practice examples for many purposes (English & German)
(including denominations in "₥")
- Highly customizable...
- Many pre-defined bitcoin bill designs available
- Also for the reverse side different designs are available (see also here)
- You can use your own customized images if you want (just the aspect ratio and the coordinates of QR codes, denominations, public address etc. are given)!
- Save/Load your complete GUI configuration settings to/from a text string
- Use self-generated private keys or your own (vanity-)keys (support for bulk processing of many keys and pages at once)
- Support for small private QR code (to allow being covered by 1 inch temper-evident holographic sticker)
- Support for large private QR code (e.g. for paper wallet)
- Support for print of black rectangle if no holographic sticker available
- ...
* Possible use cases:
- Christmas present: Customized bitcoin note with somebody's personal picture in the design, and the private key containing ... (m)BTC
- Tips: Give voucher with expiry date as supplemental tip in a restaurant/pub. Keep a copy and redeem yourself after the deadline passes.
- Educational game competition: Print 10 Bitcoin vouchers with the *same* private key - the team who redeems it first wins.
- Game Lottery: Most bills have zero or only few mBTCs loaded, but one is the main price...!
- Game Quest/Treasure Hunt/("Indiana Jones' search for the holy grail..."): Teams must put pieces of a "puzzle" together... after having solved all pieces they get the solution - this is the passphrase of a brain wallet! The team who finds the solution first and redeems the corresponding coins wins! (well ok, for this one you do not really need printed paper notes - but nice idea anyway )
- Geocaching: Populate your geocache with some mBTCs
- ...

I hope you enjoy it as much as I do!
Donations and new image designs fitting this format (aspect ratio, coordinates of print elements like denominations, QR codes, BTC address, ...) are always welcome!
Merry Christmas!
PS: More info about this tool e.g. in
this thread from 2012. The tool is based on bitaddress.org, I stripped away what is not needed and enhanced the part for the paper wallet. The bitcoin note designs are reused from tools of salfter and casascius from this forum.
