It can be wirelessly connected to the hospital's EHR/EMR system and update basic
patient information in real time such as anxiety levels, allergies, diet, and precautions
previously handwritten by medical staff on paper. The front-lit configuration sign can be
turned on for easy visibility at night. It does not require cables and displays information
as long as the installation is done, so it does not affect the operation of the department
at all. The E-paper sign does not glow by itself and does not cause light pollution to
patients. It is powered by a button battery that can last for more than 3 years by counting the update frequency every 30 seconds, so it becomes a popular solution for transferring patient room information
