But how is a photograph of a parcel going to prove anything unless it is photographed in such a way as to show where it was delivered....a photo showing the actual house/address etc.

There is still the potential for a driver to leave it at the wrong address and no-one would know....or a dishonest driver could just take a photo of the parcel and take it home with him.

Photo says delivered....sorry, we have done our job and you (the customer) lose AGAIN.
