The government’s privacy watchdog CBP says plans by Dutch Railways (NS) for the public transport chip card contravene privacy rules and has ended its discussions with the railway company, reports Trouw.

NS says it will keep personal and travel details separate but that this data will allow it to inform travellers about cheaper alternatives. The CBP says coupling this information for marketing purposes breaks privacy rules.
The new chip card is due to be introduced nationally for trams, metros and trains in 2009.
