    Abstract: The present technology relates to a medication history information management device and a method, a registration terminal device and a method, and a program that are designed to improve convenience of use while maintaining security. When there is a request for registration of a mobile terminal device, a data center associates an individual-based terminal ID for identifying the mobile terminal device with a personal identification ID for identifying the user, and records the individual-based terminal ID. The data center also associates registration date information and organization information with the individual-based terminal ID, and records the registration date information and the organization information. For the newly registered mobile terminal device, the data center further generates registration notification information in accordance with the registration date information and the organization information, and transmits the registration notification information to a member store terminal device.
