I don't know for sure, but I suspect it's because pyster will let you
through the gates with no money and leave you with a negative balance
at the other end. If there was no deposit for getting a card, people
could get an Oyster, go through the gates, chuck it away with the
negative balance and then get another Oyster for getting back home.

That's interesting. How many times are you allowed to rack up successive
negative balance on the one card?
