MMC, or MultiMediaCard, is a type of removable storage media that was commonly used in digital cameras and other electronic devices. While MMC cards are not as widely used as they once were, they are still available and can be found in some devices. However, most devices now use more advanced types of removable storage media, such as Secure Digital (SD) cards or microSD cards. These newer types of cards are typically faster and have larger storage capacities than MMC cards.
