A dual currency card in Bangladesh is a debit or credit card with two limits: a taka limit for local spending and a US dollar limit for international use, such as foreign travel and approved online payments. To use the dollar side for travel, you usually endorse dollars against your passport under Bangladesh Bank’s annual travel quota; for online payments (software, courses, subscriptions), banks allow limited international transactions subject to rules and documents. Check your bank’s current limits, fees and requirements, because these rules change.
- One card, two wallets: BDT for home, USD for abroad and approved online use.
- Travel spending in dollars is linked to your passport endorsement and annual quota.
- Online international payments are allowed within limits set by Bangladesh Bank and your bank.
- Pay in the merchant’s currency and watch conversion fees.

Card declined at the hotel in Kolkata
Imagine a teacher from Jessore on her first trip abroad. Her card works perfectly at home, so she assumes it will work in Kolkata too. At the hotel desk, it is declined. She has a dual currency card, but she never endorsed any dollars on her passport, so the international side has no limit to spend.
One visit to her bank before travelling would have fixed it. Dual currency cards are useful, but they come with steps that many people only discover at a payment counter.
How a dual currency card works
| Taka (BDT) side | Dollar (USD) side | |
|---|---|---|
| Used for | Local shops, ATMs and online sites in Bangladesh | Spending abroad and approved international online payments |
| Limit | Your account balance or credit limit | Your endorsed travel amount or the international limit your bank allows |
| Billing | In taka | In dollars, paid from a USD account or converted from taka by the bank |
Before you travel
- Ask your bank about the travel quotaBangladesh Bank sets an annual travel quota per person. Ask your bank for the current amount and process.
- Endorse dollars on your passportYour bank records the endorsement against your passport and loads or enables the USD limit.
- Activate international useSome cards need international transactions switched on in the app or by calling the bank.
- Know the feesAsk about cash withdrawal fees abroad and conversion charges.
- Carry a backupA second card or some cash in case a terminal or network fails.
Online international payments
Many people use the USD side to pay for things like software, hosting, online courses and exam fees. Banks typically allow this within limits defined by Bangladesh Bank and may ask what the payment is for. Some categories (for example certain gaming, betting or forex trading sites) are restricted. If a payment is declined, check with your bank before trying again.
Repaying the dollar side
For credit cards, the USD bill can usually be paid from a dollar account or in taka at the bank’s selling rate on the payment date. Ask your bank which option is cheaper for you and pay on time, because interest and late fees apply in either currency.
Common mistakes
- Travelling without endorsing dollars and activating international use.
- Accepting dynamic currency conversion at shops and ATMs.
- Using the card on sites your bank does not allow, leading to blocks.
- Forgetting to tell the bank you are travelling, which can trigger fraud checks.
