Act as a seasoned event planner with 10+ years of experience in hospitality and guest management. Design a smart place card that incorporates [GUEST NAME], [EVENT THEME], and [SEATING ARRANGEMENT] for a seamless guest experience. The card should use elegant typography, subtle branding, and an embedded NFC chip or QR code for instant guest recognition. Include a brief welcome message personalized to the guest's [DIETARY PREFERENCES] or [SPECIAL REQUESTS]. Ensure the design aligns with the event's [COLOR SCHEME] and [AESTHETIC STYLE], whether modern, vintage, or minimalist. The final output should be a high-resolution mockup showcasing the front (name display) and back (tech integration) of the card.
