Notebook.hu was looking for a customer-friendly customer call solution for one of their stores in Allee Shopping Center. . The essence of their concept is, on the one hand, to improve the customer experience and, on the other hand, to transform on-site idle waiting time into shopping time. Anyone who has a digital serial number is free to look around the store’s offerings while waiting. The system does not print a paper serial number here either, making it environmentally friendly and economical. The Linistry service calls customers with a monogram or first name, which, according to the representatives of Notebook.hu, is also considered an attentive, personal gesture by customers.
