The **barcode**, a staple of retail for 50 years, may soon be replaced by **QR-style codes** within two years, according to the global organization GS1.

Retailers such as **Tesco** and **Coca-Cola** are already piloting these codes, which have shown success in reducing **food waste** dramatically.

As QR codes gain traction, concerns have been raised about their potential impact on **cloud computing resources** and carbon footprints.
