Messe Düsseldorf is making it easier for visitors to GDS and Global Shoes to keep in touch, paper-free. A new service allows customers to present their visitor IDs to be scanned, and the exhibitor can see all previously stored data to get to know them. The QR code on all IDs issued for the show provides the customer's name, company and address, and the customer can add other information, such as his interests. Through the Scan2Lead program the exhibitors can see this information and make notes for their own use, such as when the customer wants to be contacted after the show. Visitors decide who gets their information. The system is compatible with smartphones. More information is available at
