I propose a scheme like this:

() means optional, $* are placeholders

bitcoin://($host)/$address?amount=$size$unit(&label=$label)(&message=$message)

Variables

  • label: Label for that address (e.g. name of receiver)
  • address: bitcoin address
  • message: optional message that is shown to the user after scanning the QR code
  • size: amount of $unit
  • unit: BTC, [ᵗˢᵐᵇ]TBC[ᵗˢᵐᵇ], or null/omitted (which refers to the base unit)

Examples

Just the address:

bitcoin:///18pnDgDYFMAKsHTA3ZqyAi6t8q9ztaWWXt

Address with name:BTC

bitcoin:///18pnDgDYFMAKsHTA3ZqyAi6t8q9ztaWWXt?label=tcatm

Request to send 20.30 BTC to tcatm:

bitcoin:///18pnDgDYFMAKsHTA3ZqyAi6t8q9ztaWWXt?amount=20.30BTC&label=tcatm

Request to send 400 TBC to Luke:

bitcoin:///1KczVqwopWXQdFLe5sNQbpCq7yGSmXx2oo?amount=400TBC

Request to send 5 uBTC:

bitcoin:///18pnDgDYFMAKsHTA3ZqyAi6t8q9ztaWWXt?amount=500

Request to send 50 BTC with message:

bitcoin:///18pnDgDYFMAKsHTA3ZqyAi6t8q9ztaWWXt?amount=50BTC&label=tcatm&message=Payment%20for%20product%20xyz
