While the original Nintendo DS hardware (including the Lite and DSi) did not have native system-level QR code scanning, the concept has become a cornerstone of the modern DS and 3DS community. Today, Nintendo DS games QR codes are primarily used by enthusiasts to wirelessly install classic titles on modded Nintendo 3DS systems or to unlock rare content in late-generation titles. 1.

If you saw "Nintendo DS games QR codes" online, they’re likely for 3DS games or require emulation/hacks. For official use, they’re no longer functional except for local/offline features in certain Pokémon titles.

Practical steps for using QR codes on a DS (historical)
The original Nintendo DS (2004) and DS Lite do not have cameras. They cannot scan QR codes at all. If you own a DSi or a Nintendo 3DS family system (which are backward compatible with DS games), those do have cameras. However, even then, you cannot simply scan a QR code and instantly download a full commercial DS game from Nintendo’s servers.

Step 2: The Redirect
You scan the code. Instead of a game file, you are taken to a link shortener (like adf.ly or linkvertise). You must click through 3-4 pop-up ads.
To use QR codes on a Nintendo DS, you generally need a system with a built-in camera, such as the Nintendo DSi, DSi XL, or any member of the 3DS family. These systems use their external lenses to "read" the black-and-white patterns, instantly translating them into data within specific games.
