What Is Contactless Payment? How Tap to Pay Works for Businesses
Learn what contactless payment is, how NFC and tap to pay work, and what businesses need to accept secure payments with compatible POS terminals.

A customer holds a credit card near a payment terminal. Another pays with a smartphone or smartwatch. Both are using contactless payment, a technology that allows customers to make purchases without inserting or swiping a physical card.
For businesses, contactless payments can offer a convenient checkout experience when supported by compatible equipment and payment-processing services.
But how does contactless payment work? Is it secure? What equipment does your business need, and how much does it cost?
This guide explains the technology behind NFC payments, tap to pay, digital wallets, and contactless POS systems, along with practical considerations for merchants.
What Is Contactless Payment?
Contactless payment is a way to complete an electronic transaction by holding a compatible card, smartphone, or wearable device near a supported payment reader.
Unlike traditional magnetic-stripe transactions, contactless payments do not require swiping the card. Customers can simply hold their device near the terminal's contactless symbol and follow the checkout prompts.
Contactless is a method of presenting a payment, not a separate type of bank account. The transaction still requires a compatible payment system and supported payment credentials.
According to EMVCo, EMV contactless technology enables compatible payment devices and readers to communicate securely.
How Does Contactless Payment Work?
Most contactless card payments use Near Field Communication (NFC), a technology that enables communication between compatible devices over a short distance.
1. The Customer Initiates the Payment
The merchant enters or confirms the purchase amount using a compatible payment terminal or POS system.
2. The Customer Taps a Card or Device
The customer holds a contactless-enabled card, smartphone, or smartwatch near the terminal's contactless symbol.
Visa recommends positioning a compatible card or device approximately one to two inches from the reader and following the terminal's prompts.
3. The Terminal Communicates with the Payment Device
The reader exchanges payment information with the card or device using NFC technology.
EMV contactless transactions generate transaction-specific security data, including a one-time security code designed to help protect against counterfeit fraud.
4. The Transaction Is Authorized
The payment is submitted through the processing system for authorization.
The merchant should confirm the approved result on the POS or payment terminal before completing the sale.
Important: A beep or animation on a customer's phone does not necessarily mean that the transaction was approved.

Contactless Cards vs. Mobile Wallets: What's the Difference?
Contactless payments can be made using different devices, but the underlying customer experience is similar.

Contactless Credit and Debit Cards
Eligible physical cards contain technology that allows them to communicate with a compatible contactless reader.
Customers can identify supported cards by looking for the contactless indicator.
Smartphones and Smartwatches
Supported smartphones and wearables can make contactless payments using digital wallets such as Apple Pay or Google Pay.
Depending on the wallet and device, customers may authenticate with a passcode, fingerprint, or facial recognition.
Employees should allow customers to complete authentication on their own devices.
Contactless Payments vs. Online Wallet Checkout
Using Apple Pay at a physical terminal is different from selecting Apple Pay during an online checkout.
In-store contactless transactions use NFC, while online wallet payments rely on a separate website or application integration.
Businesses that want to offer digital wallets both in person and online should confirm that their payment-processing setup supports both channels.
For additional information, review Apple's Merchant Integration Guide.
Are Contactless Payments Secure?

Contactless payments incorporate security technologies designed to help protect transactions and payment information.
However, no payment method completely eliminates the possibility of fraud or disputes.
EMV Contactless Security
EMV contactless technology generates transaction-specific security data, including a one-time code that helps protect against counterfeit transactions.
This is different from simply keeping a physical card out of sight.
Payment Tokenization
In supported payment solutions, tokenization replaces a card's primary account number with an alternative payment value.
That token may be restricted to a particular device, merchant, or payment scenario, reducing the usefulness of compromised payment credentials outside their intended environment.
Tokenization and EMV transaction-specific security codes provide different protections.
Not every contactless card uses the same tokenization approach as a mobile wallet.
Digital Wallet Authentication
Supported mobile wallets may use biometric verification or a device passcode to authenticate payments.
Apple Pay, for example, uses device-specific payment credentials and supported authentication features, with exceptions for certain payment modes.
PCI DSS Responsibilities
Accepting contactless payments does not automatically make a business PCI compliant.
Merchants still need to understand the security requirements applicable to their payment-processing environment.
The PCI Security Standards Council provides guidance for merchants handling payment information.
What Equipment Do Businesses Need to Accept Contactless Payments?
Businesses generally need a compatible payment-acceptance solution and an approved processing setup.
There are two broad approaches.
Contactless Payment Terminals
A compatible terminal or POS system can accept supported contactless cards and digital wallets.
Depending on the device, it may also provide transaction reporting, receipt options, refunds, and other business-management features.
Tap to Pay on Compatible Mobile Devices
Some supported solutions allow merchants to accept contactless payments directly on an NFC-enabled smartphone or tablet without an additional card reader.
This depends on the specific device, operating system, payment application, and provider.
The PCI Security Standards Council maintains standards for supported mobile payment solutions, including Mobile Payments on COTS (MPoC).

Does Contactless Payment Cost More?
Contactless payments do not automatically have a universal processing rate.
Actual costs depend on the provider, pricing agreement, card type, transaction method, and other applicable fees.
Before choosing a solution, ask about:
- Credit and debit card processing rates
- Equipment and software costs
- Monthly service fees
- Transaction fees
- Additional payment-processing charges
- Contract and funding terms
Contactless Payment Processing Cost Example
Suppose a hypothetical provider charges 2.6% + $0.10 per transaction.
For a $10 transaction:
- Percentage fee: $0.26
- Fixed fee: $0.10
- Total processing fee: $0.36
For a $100 transaction:
- Percentage fee: $2.60
- Fixed fee: $0.10
- Total processing fee: $2.70
These examples are mathematical illustrations, not Paysys pricing or industry averages.
Businesses should compare their total monthly processing costs based on actual transaction volume and average ticket size.

Do Contactless Payments Make Checkout Faster?
Visa identifies convenient checkout and faster payment interactions as potential benefits of contactless acceptance.
However, the full checkout experience depends on more than the tap itself.
A slow connection, confusing POS prompts, delayed order entry, or unclear tipping instructions can still create delays.
Before expanding contactless acceptance across locations, consider testing:
- Payment completion time
- Failed payment attempts
- Employee assistance required
- Receipt accuracy
- Transaction reporting
- Connectivity during busy periods
The goal is a checkout process that customers can use easily and employees can verify confidently.
How Do Refunds Work with Contactless Payments?
Refund procedures depend on the payment method, device, and processor.
A mobile-wallet transaction may display different card details from the customer's physical card.
For example, Apple explains that merchants may need the Apple Pay card number associated with the original purchase when processing certain refunds.
Customers can locate relevant information in Apple Wallet, and some returns may require the original device.
Businesses should train employees to:
- Locate the original transaction.
- Follow the processor's documented refund workflow.
- Confirm the refund result.
- Provide the appropriate receipt.
- Contact support when transaction details do not match.
Learn more from Apple's refund guidance.
What Should You Do If a Contactless Payment Doesn't Work?
If a customer cannot complete a tap-to-pay transaction, start with a few basic checks.
Confirm the Terminal Is Ready
Make sure the payment amount is correct and the terminal is waiting for the customer's payment.
Check the Contactless Area
Ask the customer to hold the card or device near the contactless symbol and follow the prompts.
Verify the Transaction Status
Do not immediately create a second sale if the first transaction's status is uncertain.
Check the transaction history or contact your provider before retrying.
Use an Approved Alternative
Depending on your setup, another supported payment method may be available.
For mobile businesses, include connectivity and low-battery situations in employee training.
Questions to Ask Before Accepting Contactless Payments
Before selecting a terminal or payment-processing provider, ask:
- Which contactless cards and digital wallets are supported?
- Does the solution work with my existing POS system?
- What equipment or software do I need?
- What are the total processing costs?
- How are transactions approved and reported?
- How do refunds and voids work?
- What happens if the internet connection fails?
- Which PCI security responsibilities apply?
- What support is available if a transaction fails?
Request a demonstration using your actual checkout workflow before putting the solution into everyday service.
