The post office I use are trying to keep the QR code delivery confirmation quiet. As they believe it takes away from people buying the signed for service..
For those who dont know (its my mission to inform people) everything you send with RM which has the QR code on the postage label, your receipt will come with a 16 digit reference number which can be checked for delivery. Ebay are accepting this as delivery confirmation in disputes. I normally have 1 or 2 parcels go missing per week and that has suddenly changed to 0 since the QR code came in. Recently I had a chancer try it and I sent him the code saying 'its been delivered'.. a day or so later the case was closed and I got a "oh yeah, I forgot". So, this goes to show the amount of INR cases are just utter crap.
