WowTag uses battery-free e-paper technology to bring smarter, more sustainable information displays to hotel and restaurant buffets. Unlike conventional digital displays, e-paper only requires power when the content is being updated and can continue displaying the information without a continuous power supply.

With a magnetic connector and dedicated dock, staff can quickly update dish names, ingredients, dietary information, allergens, and other buffet details whenever required. This eliminates the need for batteries, frequent charging, and disposable printed labels, making WowTag a simple, reusable, and low-maintenance solution for modern hospitality.
