Frequently Asked Questions
What does debit mean?
In banking and payments, debit means money moving out of an account. When you pay with a debit card, the amount is debited (deducted) from your bank or checking account and transferred to the merchant. A debit can be triggered at a point-of-sale terminal (typically authorised with a PIN), through an online checkout, by a recurring subscription charge, or by a direct debit instruction. The opposite of a debit is a credit — money moving into an account. On a bank statement, the debit column shows funds leaving the account; the credit column shows funds arriving.
What is a debit card and how does it work?
A debit card is a payment card linked directly to a bank or checking account. When a cardholder pays with a debit card, the transaction amount is debited from the available balance in their account — there is no credit line and no monthly bill. Debit cards work in physical terminals (verified with a PIN), at online checkouts (with 3-D Secure 2.x authentication under PSD2 in the EU and UK), and at ATMs for cash withdrawals. Common debit card networks include Visa Debit, Mastercard Debit, and domestic schemes such as Girocard (Germany), Cartes Bancaires (France), and Bancontact (Belgium).
What does a merchant need to accept debit card payments in the EU and UK?
To process debit card transactions in the European Union or the United Kingdom, a merchant needs four things: (1) an acquiring partner licensed in the target region (EU EEA-passported acquirer or FCA-authorised acquirer for the UK), (2) PCI DSS certification appropriate to transaction volume, (3) 3-D Secure 2.x integration for PSD2 Strong Customer Authentication, and (4) a technical gateway that connects the merchant's checkout to the acquirer. Payneteasy provides the gateway and integration layer that connects merchants to EU and UK acquirers under a single API.
How does PSD2 affect debit card transactions in Europe?
PSD2 (Payment Services Directive 2) requires Strong Customer Authentication (SCA) on most electronic debit card transactions in the EU and EEA. SCA is delivered via 3-D Secure 2.x and requires two of three factors: knowledge (password), possession (phone), or inherence (biometric). Merchants who do not implement SCA risk transaction declines, higher chargeback rates, and liability shifts. Exemptions exist for low-value transactions (under €30), low-risk TRA transactions, and merchant-initiated recurring payments.
What is the EU Interchange Fee Regulation and how does it affect merchants?
The EU Interchange Fee Regulation (IFR) caps interchange fees on consumer debit cards at 0.2% of the transaction value and on consumer credit cards at 0.3%. The regulation applies across all EEA countries and reduces the cost of accepting debit cards compared with credit cards. UK merchants benefit from equivalent caps under retained UK law post-Brexit. For high-volume EU merchants, accepting debit cards is materially cheaper than accepting credit cards.
Does Payneteasy support debit card processing for UK and EU merchants?
Yes. Payneteasy offers a white-label payment gateway that processes debit and credit card transactions for merchants operating in the United Kingdom, the European Union, and the EEA. The platform includes built-in 3-D Secure 2.x for PSD2 SCA compliance, multi-currency settlement (EUR, GBP, CHF, and others), connections to FCA-authorised UK acquirers and EU EEA-passported acquirers, and a routing engine that selects the optimal acquirer per transaction to maximise approval rates.
What is a debit transaction?
A debit transaction is any movement of funds out of an account to a merchant or recipient. Common examples include point-of-sale card payments, ATM withdrawals, online checkout purchases, recurring subscription billing, automatic bill payments, and vendor invoice payments. The customer's bank balance is reduced and the corresponding amount is transferred to the recipient — either instantly through real-time rails such as SEPA Instant or Faster Payments, or after a settlement window of 1–3 business days for card transactions.
What is the difference between debit and credit card processing for merchants?
For merchants, debit and credit card processing differ in three areas: (1) cost — EU debit cards are capped at 0.2% interchange under IFR, while credit cards are capped at 0.3%; (2) chargeback risk — debit transactions generally carry lower fraud rates because funds are pulled from a real balance; (3) authorisation flow — debit transactions require an immediately available balance, while credit transactions check a credit line. Both flows in the EU and UK require PSD2 SCA via 3-D Secure 2.x for most consumer transactions.
