You need to transfer season tickets or value you have purchased online to your HSL card at a large HSL ticket machine. Alternatively, you can make the transfer at R-kiosks or Alepa, S-market and Prisma store without a service fee. Please note that you cannot make the transfer at the new card readers. The ticket or value will not show on your HSL card until you have made the transfer. After the transfer, you can use your card at the new card readers as usual.
Since July 2024, passengers have been allowed to board vehicles even if they are unable to make the transfer due to the vehicle having a new card reader. This exception was in effect during the transitional period when both old and new card readers were in use. As nearly all card readers have now been replaced, this exception will be lifted effective from 18 November and season tickets and value purchased online must be transferred to the HSL card before boarding a vehicle. If you use value, you also need buy a ticket at the card reader when boarding.
