When you start accepting card payments — or switch providers — most offers highlight a single number: the transaction fee. But the actual cost of card acceptance is far more complex. There are charges buried in the fine print of your contract, fees that only show up on your first invoice, and costs that nobody mentioned during the sales pitch.
In this article, we walk through the costs that Hungarian business owners often overlook — so you can avoid paying more for your POS terminal than you need to.
This is one of the most common "hidden" items. Many providers write 12, 24, or even 36-month commitment periods into the contract. If you find a better deal or become dissatisfied, cancelling early comes with a penalty fee — potentially tens of thousands of forints.
What to watch for: Ask about the commitment period and the exact early termination fee. Some providers on the market operate with zero commitment — if flexibility matters to you, look for these offers.
Some providers charge separately for terminal setup. This might include a technician visit, terminal configuration, or even telecom line installation for countertop terminals. Others include all of this at no extra charge.
What to watch for: Specifically ask about installation costs. If you choose a portable terminal with mobile connectivity, you typically avoid separate line setup fees.
Traditional POS terminals print paper receipts, which require thermal paper rolls. While a single roll is inexpensive, busy shops can go through several thousand forints worth per month. Additional costs may include SIM card fees (if the provider does not cover them), replacement devices for malfunctions, or service charges.
What to watch for: Ask whether receipt paper, SIM cards, and device replacements are included in the monthly fee, or if you pay for them separately.
In the European Union, interchange fees on consumer debit cards are capped at 0.2%, and credit cards at 0.3%. However, these caps only apply to EU-issued consumer cards. If a tourist pays with a card issued in the United States or Asia, the interchange can be as high as 1.5–2.0%. The same applies to corporate (business) cards.
With flat-rate pricing, this does not create extra burden since your transaction fee stays the same. With interchange++ pricing, however, the higher interchange fee is passed directly to you.
What to watch for: If you run a hospitality business or tourist-facing service with many foreign guests, factor this in. Check which pricing model your offer uses.
Card networks require PCI DSS compliance for all card-accepting businesses. Some processors charge a separate monthly PCI compliance fee — or impose a penalty if you do not complete the annual Self-Assessment Questionnaire (SAQ). In Hungary, major providers typically include this in their service, but with smaller or international processors, it is worth checking.
What to watch for: Ask if PCI DSS compliance is part of the service, or if there is an additional fee.
Some providers set a minimum monthly transaction count or volume. If you fall short, they may charge an "inactivity fee" or "minimum fee." This can hit low-volume or seasonal businesses especially hard.
What to watch for: Ask about minimum volume requirements. If your business is seasonal (such as summer hospitality or market stalls), look for commitment-free options where you can pause service during quiet months.
Card payments do not land in your account instantly. Depending on the provider and your contract, payouts can take 1–5 business days. The settlement period difference is not a direct cost, but it affects your cash flow — especially if working capital is tight.
What to watch for: Ask how quickly payouts are processed. Most Hungarian providers settle within 1–3 business days, but some offer T+1 (next business day) settlement.
If your terminal breaks down, will you receive a replacement free of charge, and how quickly? Some providers include service and replacement in the monthly rental fee; others charge separately for technician visits, device swaps, or even shipping.
What to watch for: If you purchased your terminal outright (rather than renting), clarifying service terms is especially important. With rental agreements, replacement is usually covered — but verify this in the contract.
The best way to prevent hidden costs is to prepare deliberately before choosing a provider. Here are some practical steps:
Request the full fee schedule — do not just look at the headline price; ask for the contract appendix listing every charge.
Ask specifically about commitment periods, setup fees, and service terms — what is not in the offer is not necessarily free.
Compare total cost, not just the transaction fee — the cheaper provider is not necessarily the one with the lower percentage.
Use a comparison tool — on POSnavigator.eu you can transparently compare providers, pricing models, and contract terms.
The cost of card acceptance is not a single number. Beyond the transaction fee, commitment periods, installation costs, higher interchange on foreign cards, service terms, and settlement times all influence what you actually pay. If you review these factors before signing a contract, you will make a much more informed decision — and avoid unpleasant surprises.
