Digital lead retrieval is an important tool for exhibitors to measure and increase their trade show success. Scan2Lead is the leading lead retrieval system in the European exhibition industry and has already been used for more than 12 years at the largest trade shows worldwide (e.g. bauma, drupa, ISPO). With Scan2Lead the exhibitors digitally capture the contact details of their trade fair visitors and can edit and supplement the data individually. The data is immediately available to exhibitors for further processing so that they can immediately start follow-up activities and thus increase the success of their trade fair participation.
