I'm now thinking of all the other things we could have with modern technology. Biometrically-secured telephones. Borda-count voting for school superintendents. "Smart" roads that change colour when you speed. Shaving razors that tell you stock prices.
I was just thinking yesterday that we should have store doors that automagically charge you for things, no check-out required. As you walk through the door, it scans everything you're carrying or in your cart. You'd have to carry some sort of charge card that the door could recognize. It would log everything that's already been bought so if you walked in and out again you wouldn't get charged twice. Maybe the doors would have to be double (like an airlock) to protect against tailgating.
They are actually working on full cart scanners. It's still something that you would have to wait in line a little for and then input payment, but it should be a lot faster. It works on a tiny chip about the size of a grain of rice, much like what they implant into animals for indentification, that can be read from each item as you pass through the check out stand. There are still QA issues and other logistical issues to work on, but it's probably something that you will see in the next 5 years or so.
