In Europe, when you want to add more money or credits to your EURO Cup card for purchasing food, drinks, or merchandise at the stadium during the EURO Cup matches, you can use the phrase "Top up your EURO Cup card." This phrase implies that you are adding funds to your card for further use.

For example, if you are at the EURO Cup venue and you need to recharge your card, you can approach the designated kiosks or counters with the sign "Top Up Station" or "Card Recharge Station" to add money to your EURO Cup card.

By understanding and using this phrase, you can easily communicate your intention to refill your card for a seamless and enjoyable experience at the EURO Cup!
