The private travel data of hundreds of students has been passed on by Translink, the company behind the public transport chip card, to the Dutch Ministry of Education. DUO (Educational Services) requested the information to research fraud with the basic allowance by students who submit wrong information about their home address. Translink violated a policy that states that travel data can only be submitted to third parties on a request of a public prosecutor. Last May, a judge ruled that DUO violated privacy rules with these practices.
