It is a mouthful, for sure.

I have noticed a trend in Australia. First we had loyalty cards, then we had loyalty apps, and now people just tell the sales clerk their phone number. It saves keep things and remembering things. I expect this to be happening everywhere soon.

However, it is inefficient and tedious. We can make this happen faster. People wear a badge with a QR code on it, containing your phone number. It could be on an actual badge, or on the back of your phone (physically). To indicate to the checkout chick that you want them to know it (because it identifies you for their loyalty scheme), you simply hold it up or point to it – and they scan it.

Another trend is being emailed receipts and warranties instead of paper ones. That can automated in the same movement. If you want a paper receipt, you ask. Otherwise it is emailed.

Before long emails will have some kind of code in the subject line identifying them as a receipt or warranty, from any of your loyalty apps, and will be stored somewhere convenient and backed up elsewhere.
