Contactless payment allows you to make a transaction simply by tapping a contactless card or payment-enabled mobile device over a payment terminal. It’s simple, convenient, and growing in popularity: In one 2025 survey, more than half (51%) of U.S. respondents said they use contactless payment.
While there are a number of benefits of contactless payments, there are also a few key things to know about this payment method, including how safe it is.
Read on to learn how tap-and-go technology works, and how secure contactless payment is.
Key Points
• Contactless payment, or “tap to pay,” uses NFC (near-field communication) technology for quick transactions.
• Transactions are typically faster and more convenient than traditional methods.
• Security is generally enhanced through encryption and tokenization.
• Although it is becoming widely available, not all stores support contactless payments yet.
• Transaction limits may apply since contactless payments don’t require authentication.
How Do Contactless Payments Work?
Contactless payment, sometimes called “tap to pay,” uses near-field communication (NFC) to let consumers pay by tapping or waving a card, phone, or smartwatch near a payment terminal. A digital wallet stores payment information, like your credit card information, on your mobile phone or smartwatch. Both the payment device and the payment terminal have NFC chips that communicate wirelessly when they’re close together.
Instead of sending your actual card number, however, the system uses tokenization — replacing your number with a secure, random token. The token is transmitted to the payment processor, which contacts your bank to approve the transaction. If authorized, the payment is typically completed in seconds.

What Transactions Are Eligible for Contactless Payment?
For contactless credit card payment to work, both the terminal and card need to have the technology.
Many credit cards and debit cards have built-in chips, but the chip that permits you to insert instead of swipe is not the same as a contactless card. To determine if your card is able to make contactless payments, look for the universal contactless symbol — a circle with a wave inside (or WiFi symbol turned on its side) — somewhere on the card. Contactless payments are also supported by devices using Apple Pay, Google Pay, or Samsung Wallet.
To determine if a payment terminal is contactless payment enabled, check for the universal contactless payments symbol with a hand next to it on the merchant’s electronic payment terminal, device, or card reader.

Benefits of Contactless Payment
Tap to pay comes with a number of advantages — here are some of the possible benefits of contactless payment:
• Ease of use. With contactless payment, users just have to tap their chosen payment method on the terminal. There’s no swiping or inserting for the transaction to go through.
• Speed. Since there’s no swiping or inserting, contactless payments tend to be faster.
• Less stuff to carry around. If you’ve uploaded your credit and debit card information to one of the types of digital wallets, you can pay for things without carrying your physical wallet around.
• Security. Contactless payment is typically more secure than traditional magnetic-strip credit cards. Contactless payments are encrypted. This system generally makes it much harder for credit card scammers to steal people’s credit card information.
Cons of Contactless Payment
However, just like online banking and traditional banking have some pros and cons, contactless payments do have some potential drawbacks, including:
• Glitches in technology. A card and point-of-sale system might not line up from time to time, resulting in glitches.
• It’s not available everywhere. While contactless payment is being widely adapted, not every store has it. If there’s no symbol, customers will typically have to insert or swipe to pay. Or they might even choose to use money withdrawn from their checking account to pay in cash.
• Potential security concerns. Contactless payments do not require a personal identification number (PIN) or signature to authorize. As a result, lost or stolen contactless cards may be used to make fraudulent transactions. You can check with your bank to see what online banking security features they have.
• Limited transactions. It largely depends on bank policies, but because tap to pay doesn’t require authentication, there may be limits on withdrawals and purchase amounts. For more details on transaction limits, contact your bank or credit card company.
Is Contactless Payment Secure?
Contactless payments are typically safer than payments made with magnetic strip cards. However, as with many payment methods, there are still some risks involved.
How Secure Is Contactless Payment Technology?
Contactless payment technology is generally considered secure, especially when compared to the technology used for magnetic-strip cards. That’s because contactless cards use advanced security features like tokenization to protect financial data.
Tokenization replaces your card number with a unique digital token, making it difficult for hackers to use stolen information. Contactless payment may also eliminate some of the opportunities for thieves to steal – or “skim” — your credit card information, since your card never comes into contact with the payment terminal.
Are Contactless Cards Secure?
Generally speaking, contactless cards are secure, especially when compared to magnetic-strip cards. However there is the risk of theft or loss of the card. Because contactless payment doesn’t require a PIN or signature to authorize payment, if a contactless card is lost or stolen, it might be used to make fraudulent transactions. If your card is lost or stolen, you can put a freeze or lock on the card and report it to the bank immediately.
The Takeaway
While contactless payment isn’t foolproof, it can generally make purchasing transactions faster, easier, and more convenient. It’s also becoming more commonplace as a payment method, and it’s typically more secure than cards with magnetic stripes. You can weigh the pros and cons of contactless payment to determine if it’s right for you.

FAQ
Can digital pickpockets scan my contactless card?
There is a possibility that a digital pickpocket could scan your contactless card. Radio Frequency Identification (RFID) skimming is a form of digital pickpocketing in which a fraudster uses an RFID scanner, which they might hide in a bag, and stands close to you to try to obtain the data on your card. Contactless cards use encryption, which can make it difficult for your data to be stolen, but a fraudster might be able to pick up enough information in order to make purchases that are considered “card not present,” such as online shopping. You could help protect yourself against this by using wallets or sleeves with RFID-blocking technology for your cards.
Do contactless payments require a PIN?
No, contactless payments do not require a PIN for authorization. You simply need to tap or hold your card or mobile device near the reader to pay, and the transaction can go through quickly, even within seconds.
Can I accidentally pay for someone else’s items?
It’s unlikely. The retailer needs to initiate a transaction — typing in the amount and activating the reader — before payment can be made, and your contactless card needs to be within an inch or two of the reader for a payment to go through. So accidental payments are unlikely under normal circumstances.
What should I do if my contactless card is lost or stolen?
If your contactless card is lost or stolen, you can use your bank’s mobile app to put a lock or freeze on your card immediately. Then call the bank and ask them to cancel the card and issue a replacement. Monitor your account for any fraudulent activity.
Are contactless payments widely accepted internationally?
Contactless payments are generally widely accepted globally, including in Europe, Canada, Asia, and Australia. However, small businesses, small towns, and rural areas may not be set up for contactless payment.
