public transport

Like many ex pats in the Netherlands, Ideas has trouble to get to know the ins and outs of the OV chipcard, the public transport paying card . Since a week, Ideas has a personal chipcard, that provides him with 40 % discount in the weekends and out of  rush hours. The system of the card: checking in, checking out, seems simple enough. But the devil is in the details: how to check in for the fast train to Rotterdam? Do you have to check in separately for the tram? Don't forget to check out. etc. etc.
This week Ideas paid at least 10 euro's too much. And he does not feel good about this.
