Common Mistakes to Avoid with International Credit Cards

As more people head overseas for holidays or click "buy" on international websites, having the best credit card for international use feels like a must-have. It’s like a passport to making cross-border transactions! But wait! Before anyone jets off or shops globally, there are many points to note. 

Making some common mistakes while using these cards can turn dream trips or great online deals into costly setbacks. This is why it is helpful to know all the terms and conditions before navigating the world of international credit cards like a pro, to keep your finances safe and sound.

Potential International Credit Card Mishaps Ahead! 

Watch out for these common credit card mistakes when using it abroad. Keeping them in mind when using your international credit card can help you avoid paying more than necessary and enjoy savings.  

  • Not Informing the Credit Card Company About Your Plan  

If a card suddenly starts being used in a new country without the bank knowing, they may think it’s fraud and freeze the card. Imagine that happening mid-trip! A quick call or online message to the card company about your travel plans before leaving India is all it takes to avoid this.

  • The Forex Fee Fog – Being Unaware of the Charges 

Many cards add a "foreign transaction fee" (which can be between 1% and 3%) to everything bought in a different currency. This added fee can affect your travel budget without anyone noticing until the bill arrives. To avoid that, check your card’s forex fee. If it's high, looking for a card with lower or zero foreign exchange fees for international spending is a smart move.

  • Falling for Dynamic Currency Conversion (DCC)

Sometimes, a shopkeeper abroad will ask if you want to pay in Indian Rupees instead of the local currency. This is DCC. It sounds helpful, but the exchange rate used is often much higher. It’s almost always better to pay in the local currency since the card network usually gives a better rate.

  • Falling for the Cash Trap 

Pulling cash from an ATM with a credit card overseas can be very expensive. There’s usually a hefty fee right away, and interest starts piling up immediately. However, for cash needs, using a debit card instead of a credit card is generally cheaper, or you can plan ahead and carry some foreign currency. Even better if you are using the credit card for direct payment.

  • Security Snooze 

A new location doesn’t mean security goes on vacation. Not keeping an eye on the card or regularly checking for odd transactions can open the door to problems. Always be vigilant on where you are using your card, protect your card PIN, and regularly check your transaction history, especially when travelling. For this, you can use the issuer's mobile app. 

  • The "Will It Work?" Gamble 

Assuming a card will work everywhere can lead to awkward moments or trouble at the time of payment. While major networks are common in most countries, some smaller places or regions might have issues. It’s wise to check general card acceptance for the destination and always have a backup payment method.

  • The Due Date Dash 

With different time zones, it's easy to forget or miss your credit card bill's due date. Late payments mean piling up fees and penalty charges that can harm your credit score. Setting up auto-pay for credit card bills before travelling, or paying them off early, is a simple fix. Don’t wait till the last minute, clear your dues before going on the trip so you don’t face any restriction on your payments mid-trip. 

Avoiding these mistakes often comes down to awareness and having the right tools. For a good international credit card, features like clear fee structures and easy account management are the key features to look for. This is where considering a no joining fee credit card can be a smart move that can help you save money from the get-go.
