Having seen these comments on the mBarcode thread by Lardman

"That's not really what mBarcode does - mBarcode allows you to scan a barcode and use the data it contains, those apps simply store an image of the barcode on your loyalty card and allow you to scan the image on your screen at the shop rather than needing the card.

You could do this by just taking a picture of the barcode and scanning the right one as displayed by the Images application. Certainly it might be a useful app (though I only have one card that has a barcode, for Tesco, all the others have magnetic strips), but afaict it's not something mBarcode can help you with. Sorry.

What would be cool though, would be to use the location services to know which shop you're in and automagically present the right barcode image"

I wonder if anybody else as managed to get either the Tesco clubcard to work via taking a picture, I have tried before but that failed to work, or is able to port the app to Meamo as most other phone os now seem to have this app.

Just thought it would be cool to flash my N900 under the clubcard reader rather than search for the actual clubcard in my wallet!
