Over CHF 100 net purchase value, we get two points vouchers (barcode fading slip). Well, I'm in favor of this voucher not being printed out and handed in, but being stored in the checkout system. It's easier, clearer for us and less annoying. Of course, my problem is that I constantly crumple up these slips of paper in my wallet and forget them from time to time. And also of course: a gift horse etc. etc. But I would find it very, very convenient if I could see my vouchers at the subito checkout & redeem them by tapping them... or if the person at the checkout asked me if I wanted to redeem my double voucher.
