I stopped in at this service location to apply for my Lítačka card/pass. If you live in Prague, or…read morewill be here for an extended time, the Lítačka card is the transportation pass that saves you from having to buy individual tickets; and it works for the trams, trains, buses, and metros. You may apply for the card online and wait for it to come in the mail, or you may go to this "zákaznické centrum" (customer service center) to apply for and pick up your pass right away. For your first card, there is a 50 CZK fee (online) versus 200 CZK fee (in person) - so roughly about $2.50 USD versus about $10 USD.
To note: lost/damaged cards incur the same fees, but renewing an expired card costs nothing if you do it online, and 100 CZK if you renew at this center.
Also to note: take your passport and a European-sized passport photo with you. They return the photo; it is just scanned for your Lítačka card ID.
So I went in on Friday afternoon, took a number, and waited my turn. There wasn't a lot of people and service was prompt! From the time they called my number, I handed over my passport and photo, and got my card - MAYBE five minutes! I mean like SUPER FAST! Once they issue the card, you then have to fill the card, either next door or at any of the metro stations ticket office. You can do monthly (550CZK/roughly $25USD), 5-month, or yearly top ups. Needless to say, the longer time-frame is more cost-efficient.
Ok last thing from me about why to get the card - 1) You can use it as a library card as well and 2) You get discounts on at least 30 sights/attractions around Prague!
