Researchers at Radboud university in Nijmegen have succeeded in hacking into the disposable version of the new transport smart card (ov-chipkaart), a spokeswoman for the company producing the cards confirmed on Monday evening.

Trans Link Systems said some 10,000 disposable cards are currently in circulation. Smart cards are due to replace paper tickets on all trams, buses and trains in 2009.
The spokeswoman told the Telegraaf it was not surprising the disposable card had been cracked. ‘It is a low-value, one-off product… we opted for a relatively low level of security,’ she told the paper. ‘It is a product in development.’
The smart card system is being tested in Rotterdam.
Last week it emerged that German hackers had broken into part of the system used to protect the permanent smart card. That incident is currently being investigated by researchers from the TNO institute.
MPs are due to debate problems with the new system with junior transport minister Tineke Huizinga this week.
