How does this all work?

In the SaSaZu club premises, payments are made cashless using the SaSaZu Club Card. You receive this card directly at the club, where you can also load it with credit (either in cash or with a debit/credit card).

A fee of 30 CZK is charged for card activation on the spot. If you recharge online in advance (see the process below), the card is free. The SaSaZu Club Card, once loaded with credit, can also be used for other cultural events held in the club until December 31, 2023, unless stated otherwise in the club's program.

The technological solution for this service is provided by the company NFCtron.

How can I top up the SaSaZu Club Card, and where can I get it?

You can recharge the SaSaZu Club Card online using a debit/credit card or by bank transfer via NFCtron Tickets. You can also top up your credit directly at the event - in cash or with a card. You will receive the SaSaZu Club Card at the club's charging station.

How do I check my credit balance?

After each order, the seller (bar staff) will show your balance. You can also check the balance in the NFCtron mobile app, simply by reading the card or scanning the QR code from the printed information sheet you receive if you first top up your credit at the event. In the mobile app, after allowing notifications, you will receive a notification about each payment, similar to mobile banking.

Can I top up the SaSaZu Club Card again when I run out of money?

If the money on your SaSaZu Club Card runs out, you can recharge it repeatedly at the club's charging station, always free of charge. However, online recharging will not be possible during the event.

I have credit left on the SaSaZu Club Card, how can I get it back?

Refunding the remaining credit is free and unlimited to accounts in CZK and EUR. You just need to request it with a few clicks through the online receipt from the event location, via NFCtron Tickets, or using the NFCtron mobile app.

  • You can get your credit back simply by scanning the QR code from the information paper you received at the event during your first recharge.
  • Or through your NFCtron profile if you recharged the SaSaZu Club Card online before the event.
  • The easiest way to request a refund is directly in the NFCtron app.

The money will be transferred back to your bank account within approximately 5 working days from the receipt of the request. You can request a credit refund until January 14, 2024, at the latest.

What if I don't have a smartphone?

It's possible to get your money back easily on the web using a desktop computer, laptop, or tablet. A mobile phone application is not necessary for a refund, but we recommend it because of its simplicity and clarity.
