What is EMV (chip card technology)?

EMV stands for Europay, Mastercard, and Visa, the three payment networks that built the chip standard together back in the 1990s. Europay does not exist as its own company anymore, but the name stuck.

In practice, EMV just means “the chip.” It is the small square of metal on the front of most debit and credit cards. Inside that square sits a microprocessor, a tiny built-in computer, that can run a quick calculation every time you pay. Today, over 96% of card payments in the U.S. run through a chip or tap instead of a swipe.

A magnetic stripe is a passive strip. Whatever is coded onto it comes out the same way every time, forever. If a thief captures that data once, with a hidden skimmer or a stolen card reader, they can copy it onto a blank card and use it again and again. That copy problem was the biggest source of in-person card fraud for decades.

A chip solves it differently. Every time it is dipped or tapped, it runs a short exchange with the terminal and builds a one-time code just for that one purchase. Even if someone managed to steal that exact code, it is already used up. It cannot pay for anything else. Since chip cards became standard in the U.S., counterfeit card fraud at chip-reading terminals has dropped by roughly 76%.

A swipe pulls data straight off the stripe, which is why it is the fastest and the weakest of the three. A dip reads the chip through direct contact and takes a couple of extra seconds to build that one-time code. A tap reads the same chip over a short-range wireless signal, so it is both fast and just as secure as a dip. NWPB sets merchants up with terminals that support all three, so staff always have the secure option ready.

Before October 2015, if a customer paid with a counterfeit card, the card's issuing bank generally absorbed that loss. After that date, the rule changed: whichever side has the weaker technology pays.

Here is what that means in plain terms. Liability shift is just an industry name for “who pays if the card turns out to be fake.” If your terminal can read a chip and a customer still swipes a fake stripe card through it, or your terminal cannot read chips at all, you can end up eating that fraud loss yourself instead of the bank. A terminal that supports chip and tap, used the way it is meant to be used, moves that risk off your plate.

If your terminal is old enough that it only reads a swipe, or staff are told to skip the chip reader to save a few seconds, the answer is yes. It is not about a new gimmick. It is about closing off a fraud risk your current setup is quietly leaving open.

Most terminals sold today read swipe, dip, and tap in the same device, so it is a one-time hardware swap rather than a new habit to maintain. NWPB provides modern terminals that handle all three, and we check your current hardware for free as part of any rate analysis.
