The Serv-Mark might not prove as useful in more fixed restaurant setups, but it would greatly increase the efficiency and the success of service in cafes with ever-shifting seating arrangements. Qiu Wentao's concept earned him an Honorable Mention in the 2013 Red Dot Design Awards as a clever electronic adaptation to the common table numbering system.
When a patron orders his food, he takes a Serv-Mark with him back to his seat and places it on his eating surface. The cylinder displays the numeral in bright yellow, but it also projects it straight up to the ceiling in bold red. When a waitress goes to distribute the meals, she can easily locate the intended customer.
