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  Cheesy)
  • Geocaching: Populate your geocache with some mBTCs
  • ...

Screenshot of the GUI:



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.

They look great! And I really like the idea of Bitcoin Vouchers with an expiration date.
