A Lead Retrieval System is a technology used primarily at trade shows and events to collect and manage contact information from potential customers. These systems often utilize handheld devices or mobile apps that scan badges or business cards, allowing exhibitors to quickly gather leads and track interactions. After the event, the collected data can be analyzed to identify promising leads and follow-up opportunities. This helps businesses streamline their sales processes and improve their marketing strategies by focusing on interested prospects, ultimately enhancing their return on investment from the event.
