Lin says that concept comes from the current system for giving blood: whenever someone with a blood donor card needs blood or has a family member who needs blood, they are given priority. The elderly service bank would treat its creditors with the same preference.
林惠生表示，此一構想來自現有的捐血制度。凡是持有捐血卡的捐血人，一旦自己或家人需要用血時，便有優先使用的權利；加入老人服務銀行的義工亦同。
