Contactless Payments: How NFC, Cards and Wallets Work
Contactless payments are transactions without physical contact: the customer taps the card, smartphone or device on the terminal and the payment runs through NFC, the radio technology of the ISO/IEC 14443 standard. Cards without PIN pay up to €50 per transaction under scheme rules; biometric wallets have no physical limit.
Contactless instruments: how they pay and their limits
| Instrument | How it pays | Limit without PIN |
|---|---|---|
| Contactless card | NFC towards the POS terminal | Up to €50 per transaction under the schemes, above asks the PIN |
| Smartphone and smartwatch (wallet) | Wallet with biometrics (fingerprint/face) | No physical limit: biometrics replace the PIN |
| Inserted or swiped card | Chip or magnetic stripe | Always PIN or signature per the scheme |
Sources: ISO/IEC 14443 standard for NFC, payment scheme guidelines (Visa, Mastercard) on PIN-free thresholds. Exact limits depend on scheme and issuing bank.
What a contactless payment is
A contactless payment is an electronic transaction that happens without physical contact between card or device and terminal: the customer simply taps the object on the POS reader. The technology is NFC (Near Field Communication), which runs on the 13,56 MHz frequency under the ISO/IEC 14443 standard and exchanges data in a fraction of a second.
Three families of instruments accept it: cards with NFC chip (debit, credit, prepaid); smartphones with a digital wallet (Apple Pay, Google Pay, Samsung Wallet); wearables like smartwatches and enabled rings. Wikipedia notes the difference from traditional cards is the absence of physical insertion into the reader.
For the merchant the operational result is a faster queue: the customer taps, confirms, the sale closes. In fast-paced venues like bars the contactless reduces queue times at peak hours, as documented in the [POS for bars guide](/en/resources/payment-gateway-for-smes-guide).
Limits and security: when the PIN is asked
Schemes apply a PIN-free threshold for contactless operations: in Italy it is typically €50 per transaction, as stated by Visa Italia, with the exact limit depending on scheme and issuing bank. Above the threshold, the terminal asks for PIN or signature.
Digital wallets work differently: biometric verification (fingerprint or face) replaces the PIN, so the operation passes without a physical threshold. Security is handled through tokenization: the terminal never receives the card number but a single-use token, which makes intercepted data useless.
In 2026 the European Union is updating contactless operating thresholds with the new retail payments regulation (IFR extension): thresholds rise, so the PIN becomes even rarer in everyday operations.
Why the merchant has an interest in accepting contactless
Contactless is not only a customer convenience, it is a revenue lever: the transaction closes in seconds, without PIN insertion at low thresholds, and the customer needs no cash. Sector data put the average POS collection time in seconds against 20-30 seconds for a cash payment with change.
For the merchant the choice is a terminal with NFC: the RoxPay POS Smart accepts contactless cards, smartphones and wearables, with transparent IC++ pricing (€0.15 + 0.35-0.85%), no monthly fixed cost and VAT-number activation in 24 hours. Funds arrive on the business account within 48 hours.
The [contactless terminal guide](/en/resources/payment-gateway-fees-comparison) compares the NFC features of the most widespread terminals, and the [canone-free POS guide](/en/resources/payment-gateway-for-smes-guide) explains how the no-canone model works.
Contactless costs for the merchant
The cost of contactless is not different from the cost of a card payment: the fee depends on the card type and the provider's pricing model. Blended rates apply a single percentage that hides components; with IC++ you pay the actual interchange (capped at 0.2% on debit and 0.3% on consumer credit by EU Regulation 2015/751), scheme fees and a declared markup.
The wallet (Apple Pay, Google Pay) fee follows the underlying card: a wallet with a European debit card costs less than a corporate card. This is why a mix weighted toward consumer debit is cheaper for the merchant, and IC++ pricing makes it visible.
The item-by-item math is in the [credit card fees guide](/en/resources/credit-card-fees-for-merchants-guide).
Frequently Asked Questions
What does contactless payment mean?
It is a transaction without physical contact: the card, smartphone or wearable is tapped on the terminal and the payment runs via NFC on the 13,56 MHz frequency (ISO/IEC 14443 standard). No insertion of the card into the reader is needed.
How much can you pay contactless without a PIN?
Under the payment schemes the PIN-free threshold is typically €50 per transaction, as stated by Visa Italia. Above it the terminal asks for the PIN. With digital wallets biometric verification replaces the PIN, so there is no physical limit on the operation.
Are contactless payments secure?
Yes. Card data are not transmitted in the clear: wallets use tokenization, so the terminal receives a temporary code instead of the card number. Data interception risk is very low compared to magnetic stripe.
How do you accept contactless payments in the shop?
You need a POS terminal with NFC support. The RoxPay POS Smart accepts contactless cards, smartphones and smartwatches, with no monthly fixed cost, IC++ pricing (€0.15 + 0.35-0.85%), VAT-number activation in 24 hours and credits within 48 hours.
Do contactless payments cost more for the merchant?
No. The fee depends on the card used, not on the reading method: a contactless transaction with a European debit card costs the same as the same transaction with chip insertion. With RoxPay's IC++ pricing the fee components are transparent.
Do I need a new bank account to accept contactless?
No. RoxPay is not a bank and does not open bank accounts: contactless takings are credited within 48 hours to the existing business account of your company.
