Also called: Tap to pay, Tap-and-go, NFC payments, Near Field Communication (NFC)
What contactless payments are
A contactless payment happens when your customer taps a contactless card, phone, or wearable near a compatible payment terminal. The customer keeps the device, rather than handing it over, swiping it, or inserting it into the reader. Contactless cards and payment-enabled mobile devices use Near Field Communication, or NFC, to exchange payment information over a short distance.
The customer looks for the contactless symbol on the terminal, then holds the card or device near it. Visa’s guidance says 1 to 2 inches away for one to two seconds is enough. The device does not need to touch the reader. If contactless is unavailable, customers can use another supported method, such as inserting a chip card.
A tap changes how the card reaches your terminal, not the underlying processing price.
How the tap works
Your terminal reads the payment device and sends the transaction for authorization through your normal card-processing setup. A contactless card or device securely transmits account details and a one-time code that changes for each in-person transaction. That code helps reduce the risk of counterfeit-card fraud and replaying captured transaction data.
The terminal communicates with one card or device at a time. Customers carrying several contactless cards should tap the one they want to use, not their whole wallet. A contactless transaction still goes through authorization and settlement, just like another in-person card payment.
What it means for your costs
Contactless acceptance does not create a separate processing price. The underlying card or payment product determines the applicable processing costs, not whether the customer taps, inserts, or swipes. If a statement shows a new charge after you enabled contactless, compare its exact line name and amount with your prior statements. The technology itself does not explain a new fee.
Your setup cost depends on your existing terminal and point-of-sale system. Some readers need an upgrade, certification, or software update before they accept contactless cards and mobile wallets. Ask for an itemized price for any proposed hardware or software change, and confirm whether the quoted amount is a one-time cost or a recurring charge.
Verification and checkout
A Contactless CVM Limit is the transaction threshold below which the customer does not need a cardholder verification method, such as a PIN or signature. The threshold varies by country, and the research does not establish one universal US dollar limit. Above the applicable threshold, the terminal prompts for verification. Supported mobile devices can verify the customer on the device with a PIN or biometric.
Put the reader where customers can reach it and display the contactless symbol at checkout. Train staff to guide customers through a tap and follow the terminal prompts if verification is required. These steps help avoid delays without promising a particular transaction speed or bypassing security checks.
Security and your responsibility
Contactless payments use short-range communication and a changing transaction code. Visa describes contactless security as comparable to a Visa contact chip card. The short range is not a substitute for normal transaction monitoring, and contactless acceptance does not remove your responsibility to handle card transactions properly.
For transactions above the applicable Contactless CVM Limit, the merchant guide says the customer must complete verification. If a transaction above that threshold proceeds without the required verification, the guide assigns liability to the merchant. Follow the prompts on your certified terminal rather than overriding them.
What you can actually change
- Check terminal support. Run a test transaction with a contactless card and a mobile wallet. If either fails, get the exact hardware, certification, or software requirement before approving an upgrade.
- Price upgrades separately. Request a written breakdown of equipment, installation, software, and recurring charges. Compare the proposed recurring charges against your merchant statement after the change.
- Train your checkout team. Show staff where customers should tap and how to respond to a verification prompt. Keep the reader accessible and display the contactless symbol.
Frequently asked questions
Is there a contactless payment limit in the US?
There is no single US dollar limit established in the research. The Contactless CVM Limit varies by market and determines when a PIN, signature, or supported device verification is required. Follow the prompts from your payment terminal.
Do contactless payments cost merchants more?
Contactless technology does not create a separate processing rate. Your costs depend on the underlying payment product. A terminal upgrade or software change can add equipment or implementation costs, so get those charges itemized.
Are contactless payments secure?
Contactless cards and devices use short-range NFC and transmit a one-time code that changes for each in-person transaction. This helps reduce counterfeit fraud. Contactless acceptance does not replace normal transaction monitoring or terminal security.
Do I need a new terminal to accept tap payments?
Not always. Your existing terminal may already support contactless payments, or it may need an upgrade, certification, or software update. Test your setup and get the specific requirement and price before replacing equipment.
