Clone your Oyster Card

Dutch researchers are about to publish how they’ve cloned smartcards (used to gain access to government buildings, schools…) and Oyster Cards.
The publication will include all kinds of details, including the algorithm you may need for it.
The Dutch government and NPX (which makes the technology for smartcards) have complained about this publication but a court in Holland has overturned the injunction.
The real aim of the article is not to teach how to get free tube trips, but to try to improve security in smartcards.
