Do you have a 16+ Oyster Photocard? If you do...?

Go to the Post Office and ask them for an Oyster card application form. Tell them you are 16. Then fill it in and take it back to the P Office with I.D. and they'll send you one in the post. You have to top it up with money as every bus/tube journey you take it costs you �1 and you swipe it on the yellow reader. Top it up at a newsagents with cash. You don't have to use it every day, just whenever you need it until it expires. Hope I helped :)
