"Whether it’s tickets for public transport, parking, or buying refreshments on the train or cinema – if you’re a person in Czech Republic wanting to avail of any of these services and pay with cash, you could be at a significant disadvantage. In some cases, cash payment would not be possible at all, leaving citizens unable to access services. EDRi member IuRe is monitoring such cases and has pushed for a fine for services refusing cash payment in 2021."
