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.

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.

After Buy URL
It might be interesting to include an URL the user is directed to after payment.
Use case: buy digital goods for mobile devices.
Example: I want to buy a digital newspaper or app via QR code: I scan the code, pay the amount and am then redirected to a refreshing "waiting for payment" page that will show me the content when it considers the transaction valid.
