QR codes, a kind of matrix bar code, are becoming commonly used in Pyongyang as they have shown up in all kinds of ways in the last six months to mark exhibition items at a science complex, in inventory systems at supermarkets and on consumer products, a non-government organization said Thursday.
According to the website Choson Exchange, a Singaporean organization that teaches North Koreans all about the market economy, a story titled "QR Codes in Pyongyang" carried photos of a bottle of mineral water and a bottle of wine, both with a QR code attached.
The group also said a guide at the Sci-Tech-Complex in Pyongyang claimed the QR codes on some items contained additional information about the exhibited item, but this didn't seem to work.
