To determine whether the business card has effective information hierarchy, I would need to actually see the design of the business card in question. Effective information hierarchy typically includes clear delineation of important information, such as the person's name, title, company name, contact information, and possibly a logo, arranged in a way that guides the reader’s eye.
If you can describe the layout and content of the business card, I can help assess its effectiveness in terms of information hierarchy. Without specific details, I cannot accurately answer true or false.
