I am going to design a new second-hand sharing system to help refugees. Residents can read cards about their need and stories collected from refugees and give things to those in need. The cards are posted on the board in the supermarket. The back of the card is a delivery note, you can put them on the prepared box and put it in the collection box which is under the board. There is an app available, refugees can seed “need card” on the app and people also can read it.
