Well I don't.

I see these all the time on adverts and stuff and I have no idea what they mean. I don't have one of those super phones so I can't read them

I don't know why, but that's the first word that came to mind when i saw your picture on the front page.

I always thought they looked cool and should be the cover art for some sort of glitch music album.

They're QR codes. They have been a big thing in Japan for sharing web links in adverts and such. All you have to do is point your camera at a code and it loads the text or webpage. It's been a standard thing in all Japanese phones since about 2005 IIRC.

Meanwhile they exploded into popularity in America in around 2011, but naturally they can't be read by basic phones here, you have to buy a $300 "smart" phone and download a specific app for it and pay for a data plan.

The hell you talking about? Ever since there were cell phones with cameras and j2me support you could get free applications to decode QR.

If you we're up to your snatch in gold bullion maybe.

Wait, you could? I must've had a crappy phone back then. It had a camera, and it could run J2ME applications, but it couldn't run stuff that made use of the camera or the memory card.

While I can't gather any data on when the first J2ME application to read QR codes was released, a quick search shows that models released as early as 2006 are supported by the current applications that work with J2ME.
