Frequently Asked Questions
What are digital payments?
Digital payments are any payment transaction completed electronically — without physical cash. They include card payments (contactless, chip, online), mobile wallets (Apple Pay, Google Pay), bank transfers (SEPA, FAST, Wise), QR code payments, BNPL, open banking payment initiation, and emerging methods like biometric payments. The common thread: the payer authorizes and the payee receives funds through digital channels.
What is the cheapest way to accept digital payments as a merchant?
Cost depends on transaction type and market. In the EU, open banking payments (near-zero interchange) and SEPA Instant transfers are cheapest. Debit card payments (0.2% interchange cap under EU regulation) are low-cost for in-person transactions. Credit card acceptance is most expensive (0.3% EU cap + scheme fees + acquirer margin). For cross-border B2B invoices, open banking or bank transfer via Wise is typically 50-80% cheaper than card.
How is AI changing digital payments?
AI is transforming payments primarily through fraud detection (real-time behavioral biometrics and anomaly detection), authorization rate optimization (ML models predicting which transactions to approve), and intelligent routing (directing transactions to the acquiring bank most likely to approve them). On the customer side, AI powers conversational payment interfaces, automated reconciliation, and personalized payment method recommendations at checkout.
