Check your card status, balance, remember the bank hotline, or change your PIN before traveling.
Financial Preparation for Traveling
Financial readiness is crucial for every journey, especially when traveling abroad. Insufficient cash, lost credit cards, or payment issues can turn your dream vacation into a nightmare. Therefore, prepare financially before each trip to avoid unexpected financial troubles.
Contact the Bank, Verify Your Account
Before your trip, make sure to contact your bank to ensure your account is capable of international transactions and to check your balance. This is essential, as many have found themselves in trouble abroad due to unforeseen card issues or insufficient balances.

Make sure to keep the emergency phone number of your bank handy.
Save the hotline number of your bank for emergencies like lost credit cards or payment issues abroad. Besides the hotline number, inquire with the bank for alternative contact methods.
Change the PIN code of your bank card.
According to experienced travelers, it's advisable to change the PIN code of all your cards before traveling. Also, familiarize yourself with the allowed PIN code length in that country; for example, some countries only accept 4 digits instead of 6. Remember to try the new PIN code multiple times to ensure it's accepted.
Understand the regulations regarding transaction fees abroad.
Typically, a 3% fee applies to transactions conducted abroad. Additionally, there are fees for cash withdrawals abroad. If using an international bank, you'll incur another fee. Learn about these fees to decide when to use your credit card and when to withdraw cash for payments.
Carry local currency
No matter how high your credit card limit is, it's essential to have ample cash on hand, possibly in the local currency. Many transactions don't accept card payments, such as transportation and meals. Additionally, in some luxury hotels, even if you've prepaid the entire stay, they may still require a deposit for potential risks with expensive room items.
Divide your money into multiple parts
According to travel experts, it's advisable to split your travel savings (e.g., 20 million VND) into two parts. Convert one part into cash to carry (e.g., 10 million VND) and transfer the remaining part into cards capable of withdrawing cash abroad, in case the aforementioned 10 million gets spent. This ensures you don't carry too much cash, which is risky, and have a necessary backup plan for unexpected situations.
Additionally, carry a credit card (Visa or Mastercard credit card) with a reasonably high swipe limit for peace of mind and extra pocket money for transactions during the trip.
