I’ve seen many people on forums asking about the best bank cards to use when traveling to Spain. Since I’ve been living here for a few years and have hosted many visiting friends, I thought I’d share my personal experience to help you out!
The Short Answer
To sum it up: A Visa/Mastercard with no foreign transaction fees + a small amount of Euro cash is the best combination. A UnionPay card can be a good backup, for instance when providing [Spanish bank statements], but definitely don’t rely on it as your only card.
Card-by-Card Experience
Visa/Mastercard
These two are universally accepted in Spain, from large department stores and restaurants to small local shops and even automated ticket machines at tourist attractions. I highly recommend getting a multi-currency credit card with no foreign transaction fees. This way, when you make a purchase, the amount is converted from Euros to your home currency directly at the network’s exchange rate, without the extra 1-2% fee. It can save you a lot in the long run. As for cash withdrawals, while convenient, using a credit card usually incurs high fees and interest, so it’s not cost-effective. I’d only recommend it for emergencies.
UnionPay
UnionPay’s acceptance in Spain is far less widespread than Visa or Mastercard. It’s primarily accepted in places frequented by tourists, like department stores in big cities, luxury brand shops, and airport duty-free stores. Many regular restaurants, supermarkets, and small shops do not support it. Withdrawing cash with a UnionPay debit card is a good option. Many ATMs support it, the exchange rate is favorable, and the fees depend on your issuing bank’s policy; some banks in your home country might even offer the first few withdrawals each month for free. The problem is, you have to find an ATM that accepts UnionPay, which is not always convenient, a common issue for tourists managing finances, much like the process of [opening a Spanish bank account].

Practical Summary & Tips
For financial documents like the [visa bank statement], preparation is key. Similarly, here’s a simple table I’ve made for a quick comparison of cards:
| Card Type | Pros | Cons | Recommended Use |
| Visa/Mastercard (No Foreign Fee) | Extremely high acceptance, works everywhere | Some cards have annual fees; apply in advance | Primary spending card |
| UnionPay Credit Card | Occasional exclusive discounts | Low acceptance, not usable in many places | Backup card for use at supported merchants |
| UnionPay Debit Card | Good exchange rate for ATM withdrawals, some banks waive fees | Compatible ATMs not everywhere, inconvenient for purchases | Withdrawing small amounts of cash |
| Euro Cash | For tips, markets, and when card machines are down | Unsafe to carry large amounts, exchange rate loss when converting | Small payments, emergencies |
Don’t expect one card to do it all. The best strategy is to carry a reliable Visa or Mastercard for your main spending, a UnionPay debit card for occasional cash withdrawals, and have one or two hundred Euros in cash on you. This will cover almost any situation. I hope this information is helpful for your upcoming trip. Have a wonderful journey!
