At the end of the Heston Waitrose advert there is a strange square symbol which doesn't seem to be a picture or anything. The symbol is also on a letter that I recently received from the local health authority reminding me about an appointment. Does anyone know what the symbol is for?
Waitrose are using a QR Code at the end of the Christ mas TV ad to promote their app, available for iPhone and Android handsets. QR Codes also feature prominently in their print adverts, including explanations of how to scan the codes.
Hmmm ... I have a £2.98 mobile which does calls AND text messaging. That ''whoosh'' you may have heard earlier was iPhone technology going right over my head, lol
