I have some doubts abut validation Brussels jump card 24h/48h/72h .
- If I buy one of these cards I should validate it for the first time in the red machine with white eye?
- And then I am not sure if I should validate this card every time I board a tram?
- And when I get off the tram I also should insert this card into orange machine in the tram?
Could someone help me because it seems a bit complicated when i try find information on the internet.
