Debit vs credit: which should a US traveler use?

Both pay the same price for the same eVisa, billed in the same US dollars, and both deliver the same printable PDF in 3 business days. The choice is about protection and timing, not about cost. For a single traveler with a comfortable checking balance, debit is genuinely fine. For anything more involved — a family of four, a tight balance, a card you want a chargeback safety net behind — a credit card pulls ahead.

The strongest argument for credit is chargeback protection. US credit cards under the Fair Credit Billing Act give you the right to dispute a charge for goods or services not delivered, and your liability for unauthorized charges is capped at $50 (most issuers waive it entirely). Debit cards carry consumer protections too, but they are weaker and slower, and a disputed debit charge means money that has already left your account while the bank investigates. Paying a foreign-merchant visa fee on credit keeps that money in your pocket until everything is confirmed.

The second argument is the float. If you are paying for several travelers at once — say four eVisas at $80, which is $320 in one sitting — a credit card lets the charge ride until your statement closes. A debit card pulls all $320 from checking immediately. Neither is wrong, but if your balance fluctuates, the float buys you breathing room you do not get with debit.

Where debit clearly wins is discipline and simplicity: you are spending money you already have, with no interest, no balance to pay down, and no temptation to carry the charge. If you do not own a credit card at all, debit is a complete answer — millions of Americans pay for the Cambodia eVisa on a debit card every year without a hitch. And if you would rather not type a card number on a travel site at all, the PayPal, Apple Pay, and Google Pay options tokenize the payment so your raw card details never touch the checkout, while still drawing on the debit card you already have linked.

Prepaid cards and Visa gift cards: proceed with caution

Prepaid debit cards and Visa or Mastercard gift cards are the gray zone. Some go through without issue; many do not. They carry a Visa or Mastercard logo, so on paper they look identical to a regular debit card — but the issuers behind them often block international online merchants, and a fair number reject any transaction that needs a billing address or ZIP they were never registered with.

The bigger risk with a gift card is that it is a closed pool of money. A regular debit card draws on a checking account you can top up; a $100 Visa gift card holds exactly what was loaded onto it. If the eVisa charge fails partway — a fraud screen, a ZIP mismatch, a partial authorization that does not clear — the funds can sit in limbo for days, and you cannot simply add more to push the payment through. We have watched travelers burn an afternoon trying to make an under-funded gift card cover an $80 visa.

If a prepaid or gift card is genuinely all you have, two things make it more likely to work. First, register the card with your name and billing ZIP on the issuer's website before you pay, so the address-verification step matches. Second, confirm the card balance comfortably exceeds the price — a $90 Business eVisa on a card holding exactly $90 leaves no room for a foreign-transaction quirk. Where you have the choice, a standard bank debit card or a credit card is far less fuss.

One more note for travelers carrying an American Express card: Amex is accepted at the Cambodia eVisa checkout alongside Visa and Mastercard, so an Amex credit or charge card is a perfectly good fallback if a prepaid card stalls. The Amex card options for Americans guide covers where it works and the one or two places a Visa or Mastercard is smoother.

When a debit card payment fails — and how to fix it fast

A declined debit card at the Cambodia eVisa checkout almost never means the visa service rejected you. It means your bank stopped the charge, and there are only a handful of reasons it does. Work through them in order and the vast majority of US debit declines clear in a couple of minutes without leaving the page.

• International purchases switched off. The most common cause. Open your banking app, find card controls, and enable international or overseas online transactions, then retry.
• Suspected-fraud hold. Your bank sees an unfamiliar overseas charge and freezes it to protect you. A travel notice in the app, or a quick call to the number on the back of the card, releases it.
• Insufficient funds. A debit charge needs the full $80 or $90 sitting in checking right now. If the account is short today, move money in or pay after your next deposit clears.
• Billing ZIP mismatch. The checkout verifies the ZIP tied to your card. Enter the ZIP on your bank statement, not the one where you are staying.
• A typo in the card details. One wrong digit in the long number, expiry, or three-digit security code fails the whole authorization. Re-key it slowly.

If the charge keeps failing after international purchases are on and the funds are confirmed, the cause is almost always a fraud hold on your account — and that is its own quick fix. The bank fraud-hold guide for Americans shows exactly how to clear an overseas-charge block by phone or in-app, usually in under five minutes, so you can complete the payment on the same visit. Whatever happens at the bank end, your application data is saved; a failed charge does not erase the form you already filled in.

And to be clear about what a failed charge costs you: nothing. A declined debit attempt does not bill you, does not start a partial application, and does not count against any limit. You can switch to a different card or wallet and try again immediately. The price is the price — $80 Tourist, $90 Business, billed in US dollars — and no surcharge is added for using debit rather than credit.

Bottom line before you pay

Pay for the Cambodia eVisa on a debit card with confidence, as long as two boxes are ticked: it carries a Visa or Mastercard logo, and international online purchases are switched on in your banking app. The full $80 Tourist or $90 Business fee leaves your checking account the moment you confirm, billed in US dollars, and you get the same printable PDF approved in 3 business days that a credit-card payment buys.

Reach for a credit card instead when you want the stronger chargeback safety net, when you are paying for a family in one sitting, or when your checking balance runs close to the line and you would rather not pull the money today. Steer clear of under-funded prepaid and gift cards unless they are your only option and you have registered the billing ZIP first. Every one of these paths leads to the same approved eVisa — the choice is purely about which way you would rather move the money.

Next steps and related reading: apply for your Cambodia eVisa when your card is ready, review the full accepted payment methods for Americans if you want every card and wallet option, keep the credit-card decline fixes guide handy in case a charge stalls, and bookmark the Cambodia visa hub for US citizens as your single reference for cost, documents, and processing.
