@ Kingshead2 - QR codes eh? I got the App for my iPhone but the only example I've seen apart from yours today was one on the OH's credit card statement so not exactly thrilled or au fait with the practice yet! I have a standard question when faced with new technology to be sorted into 'useful' or 'ignore' categories: 'can it make me a cup of tea'? You guys offer an attractive 3rd alternative.
