Have your say

I’m really impressed with the new scanning machines that let you do self-checkout and check-in of books at the Gosport Discovery Centre.

They’re so much easier to use than the scanners at the supermarket.

The library’s new machines boast the amazing capability of being able to detect the titles of the books stacked one on top of another – no faffing about with bar codes or swiping needed.

You simply place your books on the glass plate in a vertical pile and, hey presto, you’re done.

Wouldn’t it be cool if supermarkets could adopt a similar system, and we would no longer have to fill the checkout conveyor belts with all our goods Generation Game style? Queue-busting extraordinaire.
