It would actually be easy enough for Walmart to switch to paper debit cards that had the amount of the card printed on the front. When you used that card, the cashier simply gave you lower-denomination of cards (say, a $5 debit card when you paid for a 5 dollar item with a $10 debit card).

Once this practice became pervasive enough, unfortunately the government would have to step in to create rules and regulations as to how all the printing would appear, and to prevent fraud. I suggest they mandate the use of engraved printing plates; green magnetic ink; and heavy cotton rag for the card. Oh, and to certain security features like holograms, watermarks, embedded plastic strips, etc.

My god, the level of convenience we'd enjoy would blow away any other form of paying for goods and services literally overnight.

Let me guess, you don't get vaccinated, either...

Are you just as histrionic over Lois Lerner's missing emails?

That was awful. Pick up just about any Harry Turtledove book for a more thoughtful take on the subject.

You need one of those gay European man purses to carry around all your loose change. Then it makes sense, I suppose.

Peasant Han: "Honest officer! Our child was sold into slavery over a year ago!"

Officer Zau kicks over the wood stove, lifts open a patch of the tile floor and shines his light into the darkness below. A dozen eyes shine back.

Officer Zau (screaming): Zui cha. Chaqu. Yongyuan!

Officer Zau unholsters her Type 15 pistol, takes aim at Han and puts her finger on the trigger.

Is there any other kind?</snark>

I recall an old Science Fiction story along the same lines, back in the early 80s.

The protagonist was a young man in a third-world middle-eastern shitehole. He was tired of war, of losing friends and families, when he had a revelation: the "Blue Hats" (UN) were neutral, so if he joined their "army" he'd be relatively safe and wouldn't have to fight any more.

So, he obtains a discarded steel pot and paints it blue. Reveling in his newfound "immunity," he convinces his friends and neighbors to do the same. Even the other side starts doing it until everyone is a Blue Hat -- and peace breaks out for the first time in living memory.

I forget how it ended, but the gist was that the First-World was using the Third-World as a "live culture" of warfare, to keep the former's own troops trained and budgets justified. The old sides were eventually convinced to go back to fighting one another.

To this day, males 18+ must register. Those who do not cannot receive Federal financial aid, nor work as a GS or contract employee for the Fed.

Did it do a 4G inverted dive?

You went long on Demand Media stock, didn't you?

That butthurt's gotta burn!

Pfft. I invented the wheel with round corners.

Ah, thanks.

Hooray! Congrats!
