The @CommuterLine ticket that I always use is the Multi Trip Ticket or Kartu Multi Trip (KMT). This multi trip ticket can be use as many as like to travel with @CommuterLine. The condition is only your balance can not be less than Rp. 7.000.
You can buy the KMT at the ticket counter. The price for the first KMT is Rp. 50.000 with Rp. 30.000 balance. I am not sure, if you return your KMT you can get your Rp. 20.000 for deposit, but you can keep the KMT with no expiry date. It’s a life time card basically.
The procedure to use your KMT is the same with the THB card. Go to ticket counter and ask for the KMT and pay for Rp. 50.000
The @CommuterLine ticket price is Rp. 2000 for the first 5 stations, excluded your departing station, and Rp. 500 for every three station.
Get into the electronic gate by tap in your KMT with your left hand and get out from the Electronic Gate by tap out your KMT with your right hand.
You can only reload your balance in the ticket counter with minimum for Rp. 5.000 and maximum Rp. 1.000.000.
There are another pre paid card issued by several bank that can be used as KMT such as; Flazz Card (BCA), E Money (Bank Mandiri), Brizzi (Bank BRI), and Tap Cash (Bank BNI).
