Hi all.

I’ve been looking at building a mobile application that will store, store-card details.    As most store cards have barcodes on them,  I thought it would be cool, if you could present the barcode of your card on the screen of your mobile device.

I’ve just found out to my peril that laser-barcode readers cannot read barcodes off of an LCD screen.  Try it if you don’t believe me -

clip_image002  has no such problems as Microsoft Tag was designed to be read by a camera phone, which works great.

I guess by "laser" you mean 1D scanners
2D scanners read it ok!
just tested with Intermec CN3 device, but sure any other 2D scanner would read just as well... we actually played a "barcode shooting game" once - all presented on LCD screens...

(and 1D scanner won't be able to scan a Microsoft tag either because that is 2D!! ;)

Yep, I did mean 1D scanners.

I wonder if the supermarkets use 2D?
