Problem:

You wish to pay a friend with Bitcoin.

You have saved your password for MyBitcoin.com except for the last 3 letters into your mobile phone memory to save time,

but the Bitcoin address is still very long to type in.

How can this be better?

Barcodes.

There are 2 sections to this problem:

1) Generate a barcode for a bitcoin address.

2) Read a barcode using a mobile phone camera.

There are apps that can read barcodes (http://scan.jsharkey.org/) but what I'm looking for is one that runs in the background and types in the barcode number into the webbrowser. I haven't found that yet. Here's a starter on how you might make that:

You don't need an Android phone to make an Android app. See this article:
http://news.softpedia.com/news/How-to-Run-Android-Applications-on-Ubuntu-115152.shtml

You can run an emulator on your linux or Windows box straight away, including using a PC connected webcam (see http://scan.jsharkey.org/ )

Somebodies already on the barcode scan API:
http://code.google.com/p/zxing/

It should be a simple feat to use that for copy the results from zxing into the copy/paste buffer for easy copying into the web browser.

2) Making your own Bitcoin address barcode.

Here's the list of barcode types useable with zxing:
* UPC-A and UPC-E
* EAN-8 and EAN-13
* Code 39
* Code 93
* Code 128
* QR Code
* ITF
* Codabar
* RSS-14 (all variants)
* Data Matrix
* PDF 417 ('alpha' quality)
* Aztec ('alpha' quality)

I'm now looking up how to make these....

there seems many barcode scanning app for phone , which one to choose is the best way to do such a thing ？
