Well I never. I just happened upon the tesco online app, and noticed an interesting claim. Scan and add. So, intrigued of Halifax, I downloaded it and went down to the kitchen in search of something to scan. So, basically, you click the button and the camera starts up with guides into which you fit your barcode. Once it has it, the guide turns green and hey presto. In seconds the website returns the product details of your chosen item. I am suitably impressed!
It’s like magic! Obviously you need a camera phone to do it. Don’t think I can make my I-Touch order from Tescos.
