index cards

Index cards are small, rectangular sheets of sturdy paper used to organize information. They’re commonly employed for studying, note-taking, or presenting data, allowing users to write a key point, fact, or question on one side. Their portability makes it easy to arrange, review, and shuffle information quickly. They’re a practical tool for keeping concepts clear, practicing speech, or categorizing ideas without the need for digital devices. Essentially, index cards serve as tangible, manageable units of data that help improve memory, organization, and communication.
