Also, consider using SI prefixes. They are standard throughout the world (except America). Genjix 08:04, 10 January 2011 (GMT)

  • SI/decimal is the inferior competition/enemy of the superior Tonal system. That is, to be avoided. (Chinese is a standard language throughout most of the world too! And whatever the currency of China is-- should we not use bitcoins??) Luke-jr 15:05, 10 January 2011 (GMT)
Exponents
  • Wouldn't it be better if we used the more standard "e" to represent the exponent? e.g. 5e8 = 500,000,000. Weavejester 11:18 PM, 18 April 2011 (GMT)
An older draft used this, but when implementing, it was quickly noted to conflict with the 'e' hexadecimal digit. --Luke-jr 16:04, 19 April 2011 (GMT)
Thanks for the response! I noticed that flaw shortly after I asked the question, but it looks like the wiki lost the update I posted. Out of interest, what's the benefit for allowing both decimal and hexidecimal notation? Weavejester 20:02 PM, 19 April 2011 (GMT)
Fallback URI

On Android an app can register to open with a normal web URI. This has the advantage of acting as a fallback URI in case there is no app that supports bitcoin:. For example we could propose https://en.bitcoin.it/wiki/Send/<address>[?][amount=<size>][&][label=<label>][&][message=<message>]. If the user had a mobile app that supported bitcoin it would have registered https://en.bitcoin.it/wiki/Send/ and be launched. If the user did not have such an app their browser would launch and be directed to https://en.bitcoin.it/wiki/Send/. This page could then inform the user about various apps that support bitcoin transfers and possibly have a link to MyBitcoin as well. Maybe https://bitcoin.org/Send/ would be more appropriate, though that one might not be updated often enough.

  • iPhone support

There is even a way to have this work on iOS devices. Have the web page redirect to the standard bitcoin: scheme. If an app is present to support this the app will launch, if not the browser the will stay open at the explanation page.

  • Upshot

This fallback proposal will make bitcoin QR codes meaningful regardless of if the user has a bitcoin app installed.--BitMark 16:05, 2 April 2011 (GMT)

Use-cases - buy this link

On the buy-this link, perhaps we should also incorporate an optional transaction id or something which would be passed along to the bitcoin client. Not really transaction but some sort of arbitrary data, only meaningful to the merchant. Something an online merchant can use to verify which transaction it has received is relevant to a purchase.
