Tourist Scams in Prague: What to Watch For and Where
Prague's tourist problem is almost entirely financial, and most of it flows through one industry: currency exchange. Understand how crowns are supposed to reach your pocket and the city becomes one of Europe's easiest capitals.

Problem zones at a glance
- Karlova street & the exchange gauntlet High The lane from Charles Bridge to Old Town Square is lined with 'zero commission' exchange offices — the city's signature trap.
- Old Town Square at the clock hour High The Astronomical Clock crowd is Prague's densest pickpocket moment, every hour on the hour.
- Wenceslas Square after dark Moderate Street money changers (always a scam), club promoters, and inflated late-night bar bills.
- Charles Bridge crowds Moderate Classic crowd-crush lifts among the portrait artists and selfie stops.
- Tram 22 & the castle queues Moderate The scenic tourist tram is the pickpockets' commute too — peak at boarding.
The short version
Prague is compact, walkable, and physically safe to a degree that surprises visitors — and it monetizes tourists through paperwork instead: exchange spreads, conversion tricks, and the occasional creative taxi meter. Nearly everything on this page is defeated by two habits: pay by card while declining every conversion offer, and never change cash without knowing the exact crowns you’ll receive. Master those and Prague’s scam layer shrinks to pickpocket-awareness at the clock show.
The scripts you’ll actually meet
- The zero-commission exchange. The big window number is the rate for buying crowns from you, not selling them; the commission is genuinely zero because the margin — sometimes 30% — lives in the spread. One question collapses it: “How many crowns will I get, total?” Full arithmetic →
- The street money changer. A man near Wenceslas Square offers a rate better than any office. The wad he hands over is padded with expired notes or Belarusian rubles — and in the deluxe version, “plainclothes police” arrive moments later to “check your currency” and confiscate it. Both halves are the same crew. Indoors, receipt, or nothing.
- The tourist ATM. Freestanding bright-blue machines in tourist zones charge premium fees and push their own miserable conversion rate. Use bank-branch ATMs and always choose “charge in CZK / without conversion” — the same rule as every card terminal in town.
- Taxi overcharging. Prague’s taxi sharks were once legendary; Bolt, Uber, and Liftago have mostly ended the era. Hail by app and the problem is history; from a street rank, confirm the meter before moving. The universal script →
- Clock-crowd pickpocketing. Every hour, hundreds of upturned faces gather under the Astronomical Clock — the easiest working conditions in the city. Watch the show with your bag in front; the lift teams work the back rows. The mechanics →
Money and getting around
Czechia uses the koruna (CZK), not the euro — and shops that “helpfully” price in euros set their own poor rate, so pay in crowns everywhere. Cards tap almost universally, including transit machines, which means many visitors sensibly never touch cash at all. Transit itself is excellent and honest: metro, trams, and validated paper or app tickets — just remember plainclothes inspectors are real here (badge on request), and an unvalidated ticket is your fine, not a scam.
What it looks like
Every Prague money trap shares one move: an intermediary inserts a conversion you didn’t ask for. The terminal offering to charge your card in euros, the ATM offering “guaranteed conversion,” the exchange window leading with the wrong rate, the shop menu priced in EUR. Each conversion belongs to them, not you.
Do this instead
Always transact in crowns: choose CZK on every terminal and ATM screen, decline every ‘convert for you’ offer, and let your own bank do the math — its rate beats the street’s every time. For cash, ask the total-crowns question before money changes hands, keep the receipt, and remember the posted cancellation window if a number surprises you.
Warning signs, in general
- Any rate displayed bigger than the transaction is the wrong rate — the number that matters is the crowns in your hand.
- Anyone exchanging money outdoors, at any rate, is running one of two scripts, and the second involves fake police.
- A bar or club with a promoter outside and no prices inside runs Wenceslas Square’s mild version of the bar-bill trap — same rule: you pick the venue.
If something happens
- Emergency: dial 112.
- Bad exchange: act fast — with the receipt, Czech consumer rules give you a short cancellation window (the honest offices post it; three hours is the figure to remember). Return, request reversal, and involve the Czech Trade Inspection (ČOI) if refused.
- Street-changer or fake-police loss: report to the state police immediately with locations and descriptions — these crews work fixed patches and the reports accumulate.
- Pickpocketed at the clock or on tram 22: the standard first-hour checklist →
Quick answers
Is Prague safe for tourists?
Very — it's one of Europe's safer capitals for physical crime, and walking the center at night is routine. Prague's risks are financial: predatory currency exchange, street money changers, occasional taxi overcharging, and pickpockets at the big crowd moments. Guard the wallet transactions, not your person.
How should I exchange money in Prague?
Ideally, barely at all — cards are accepted nearly everywhere, and bank-branded ATMs (not the freestanding tourist ones) give fair rates if you decline the machine's own conversion offer. If you want cash exchanged, ask any office one question first: 'How many crowns will I receive for this amount, total?' — and walk out if the answer differs from the big number in the window.
Are the 'zero commission' exchange offices a scam?
The commission really is zero — the margin hides in a sell rate 15–30% worse than the fair rate, often displayed so the attractive buy rate catches your eye. It's legal, signposted, and catches thousands of visitors weekly. Czech law does give you a cancellation window on exchange transactions (keep the receipt and act within three hours), which the honest offices post prominently.
Should I ever change money with someone on the street?
Never — the Prague street changer is a 100% scam, no exceptions. The 'great rate' bundle is padded with worthless or foreign notes, and a variant adds fake plainclothes 'police' who confiscate your cash for 'checking.' Real exchange happens indoors with a receipt; real police don't inspect tourists' wallets on the street.
