Esta versión renovada de la aplicación permite a los hoteles integrar dispositivos BLE manteniendo los niveles de seguridad establecidos. El sistema admite tres perfiles de usuario diferenciados, lo que facilita su adaptación a las operaciones del establecimiento sin comprometer el control ni la trazabilidad. De forma predeterminada, las llaves electrónicas se generan y distribuyen desde el software de recepción. Para casos puntuales o situaciones de emergencia, el administrador de la instalación puede crear y enviar llaves de apertura vía Bluetooth desde su smartphone. Tras la ejecución de una auditoría, los registros se sincronizan automáticamente con el servidor y quedan disponibles tanto en el software de gestión como en la aplicación para los usuarios con perfil administrador.
