Card-present payments have come a long way from the magnetic stripe. Today, most in-person transactions run through one of two technologies: EMV (Europay, Mastercard, and Visa — the chip in your card) or NFC: (the contactless, tap-to-pay technology behind Apple Pay, Google Pay, and Samsung Pay). Both are more secure than a swipe, but they work differently, carry different liability implications, and matter to your business in different ways.
Here's what merchants need to know about each.
EMV stands for Europay, Mastercard, and Visa, the three companies that originally developed the standard. In practice, it refers to the chip embedded in most modern credit and debit cards.
Unlike a magnetic stripe, which stores the same static data every time it's read (making it relatively easy to copy through card skimming), an EMV chip generates a unique cryptographic code for each individual transaction. That code is useless to a fraudster after it's been used once, which is what makes chip cards so much harder to duplicate.
One important limitation: EMV only works in card-present scenarios. If a card is keyed in or used online, the chip isn't involved — those transactions rely on other safeguards instead, like tokenization and 3D Secure, to stay secure.
What EMV Protects Against
This is the part that directly affects your bottom line.
Before EMV became standard in the U.S., the issuing bank absorbed most of the liability for in-person card fraud. That changed with the EMV liability shift: if a fraudulent transaction occurs at a terminal that isn't EMV-compliant, the merchant is now responsible for that loss, not the issuing bank.
The good news: merchants who use EMV-compliant terminals, process at least 95% of transactions through them, and stay current on PCI compliance are still covered by full fraud protection. The liability shift only kicks in when a merchant is running non-compliant hardware.
If you're not sure whether your terminals are up to date, that's worth checking sooner rather than later. Data breaches and fraud losses are a lot more expensive than a terminal upgrade. These real-world examples show what's actually at stake.
NFC stands for Near Field Communication. It's the technology that lets a customer pay by tapping or hovering their phone (or a contactless card) near a reader. No insertion, no swipe required.
NFC payments use the same level of encryption as EMV chip transactions, but they're faster. The whole thing takes about a second. It's what powers Apple Pay, Google Pay, Samsung Pay, and contactless cards, and it's increasingly what customers expect, especially younger shoppers who rarely carry physical cards at all.
Merchants who want to accept NFC payments need a terminal with a contactless reader. Many modern terminals include this by default, but it's worth confirming yours does.
Both are secure. Both are better than a magnetic stripe. The main practical differences:
Most modern terminals support both. If yours doesn't, it's worth asking your processor about an upgrade.
Q: What does EMV stand for?
A: EMV stands for Europay, Mastercard, and Visa. It refers to the chip technology used in modern credit and debit cards to generate a unique code for each transaction, making it much harder for stolen card data to be reused.
Q: What is the EMV liability shift?
A: The EMV liability shift changed who's responsible for fraudulent in-person transactions. Before EMV, issuing banks absorbed most fraud losses. Now, if a merchant is using a non-EMV-compliant terminal and a fraudulent transaction occurs, the merchant bears the liability.
Q: Does EMV work for online payments?
A: No. EMV chip technology only applies to card-present transactions where the physical chip is read by a terminal. Online and keyed-in transactions use different security methods.
Q: What is NFC and how does it differ from EMV?
A: NFC (Near Field Communication) enables contactless payments. A customer taps their phone or card near a reader and the transaction is complete in about a second. It uses the same encryption standards as EMV but doesn't require card insertion. NFC is what powers Apple Pay, Google Pay, Samsung Pay, and contactless card payments.
Q: Do I need a special terminal to accept NFC payments?
A: Yes, your terminal needs a contactless reader to accept NFC payments. Many modern terminals include this capability, but not all do, so check with your processor if you're unsure.
Running EMV-compliant hardware isn't optional anymore. It's where liability lives. And accepting NFC is increasingly a customer experience issue: more people are paying with their phones than ever, and a terminal that can't accept a tap is a friction point at checkout.

Propelr works with merchants of all sizes to make sure their payment setup is secure, compliant, and ready for the way customers actually want to pay. If your hardware is overdue for an upgrade, let's talk.
This post dissects everything that happens during a card transaction, step by step, starting with the moment a customer pays and ending when funds are deposited into the merchant's account. Along the way, it covers authorization, batching, settlement, and where interchange fees come into play.

Ever wonder what actually happens when a customer swipes their card? Five key players work together behind the scenes: the issuing bank, the card brands, the processor, the payment gateway, and the sponsor bank. This breakdown covers who's who and what each one is responsible for.
Propelr has partnered with Atrium Campus, a leading provider of cloud-native campus card management solutions, to embed secure payment acceptance directly into the Atrium platform, enabling institutions to seamlessly integrate modern payment capabilities into their campus technology ecosystem.
