What To Do With Old Oyster Cards
If you have finished using your Oyster card, like I did, when I got to an age that entitled me to a Freedom Pass or perhaps you are sadly leaving London for good, there are two things you can do with it.
You can donate it to charity by dumping it in a box like this one at Liverpool Street station.
Railway Children is an international charity that fights for children who live on the streets.
Or you could ride several times on the Emirates Air-Line.
