Ticket Types

All tickets are period tickets. The shortest period is for 75 minutes and starts when you first use the ticket. The longest period is one year and you need a plastic card for that type.

Period lengths:

75 minutes
24 hours (1 day)
72 hours (3 days)
1 week
1 month
3 months
1 year

All tickets are available at both full and reduced price. (You'd need 2 full and at least 2 reduced see below regarding children)

If you get a blue plastic card you can load money onto it and then get 75 minutes tickets when you use it.

Children

Childen under 7 don't need a ticket if travelling together with someone that has a ticket. Almost same for 7-11 years old children during weekend (Friday 12:00 to Sunday 24:00) but to go for free they need to travel with an adult/senior.

Ticket Formats

You can't get all tickets in all formats. However, all tickets can be loaded onto the blue plastic SL Access Cards which can be bought everywhere.

These are the ticket formats:

Mobile Tickets, using the official SL app. They are using optical barcodes. Only 75 minutes and 24 hours tickets available. You scan them on special scanners, but if there are no scanners you show them to a person.
Paper Tickets, can't be reloaded. They are using RFID.
SL Access Card, the blue card. Can have money on it and all tickets.

Group Travel

If you have the SL Access Card you can have multiple active tickets on the card. Simply tell the person at the gates, or the bus driver, that you are a group travelling on the same card and he will activate multiple tickets on the card. You will then have to use the manual gates the rest of the trip and always say that you have a "group ticket".

If you're staying a shorter period and you have juice in your phones, I'd suggest using the mobile tickets.
