Recently, smartphones and tablets have been used for collecting records of patients' compliance with drug regimens at medical sites. However, it is difficult for many elderly patients to operate these devices. Most medical facilities are also unable to prepare and distribute these devices to all patients. In this study, we have introduced a novel and simple electronic device system to evaluate its usefulness to patients. This new device is a paper card device equipped with an electric circuit board and a memory chip, which is employed to record the times at which patients take medications and the patients' condition. These simple paper electric devices have the potential to be used in various scenarios for monitoring medical and daily life activities. Using the new devices would enable effective and cost-effective medical care.
