New idea: An Efficient Line

I hate people who won't join the 21st century. I don't understand why so many people still pay for things with checks. Visa should have me on their commercials about their check card because I can't stand people who insist on slowing down the whole line because they insist on paying with checks. Not only do they have to write down all the information but then the cashier inevitably has to ask for ID and then write down all the information.

Why don't they just get a check card. I have one. It makes my life simpler. It cost me nothing to use and it comes directly from my bank account. In fact, it cost people money to write a check because you have to buy new checks that much sooner. I also get the added benefit that since its a Visa purchase, if I have a dispute Visa will help me out with it.

Can someone please tell me why people still pay with checks?

I think they should have an efficient line. Not an express line, an efficient line. This line would be for people who are

1. Paying by credit card only (no Cash. Cashier has to make change)
2. Have 5 or less items (10 is way too many)
3. Are not going to ask questions
4. Are not going to get a warranty
5. Know exactly what they have is what they want.

In other words the cashier is not allowed to do anything or help anyone who doesn't simply walk up to the cashier, hand over their items and credit cards, sign, and leave. Any deviation from that and that person gets booted from the line.
