The looming deadline for EMV compliance is putting pressure on c-stores and petroleum retailers and they cannot afford to ignore the steep economic risk associated with non-compliance. In this post, EMV and its effects since the year-old deadline will be discussed. EMV Adoption Stats. According to a survey released last month by The Strawhecker Group, only 44% of merchants had.

What EMV data do you need? Name, card number, expiration and usually the tags for building the cryptogram

Where do you use it? You use it to populate Field 55 in the ISO 8583 message. Details on iso8583 for programmers

How do you use EMV data? Field 55 is a TLV field (tag-length-value). You can decode it with our EMV TLV decoder

Since its introduction to the United States in 2011, EMV chip technology has dramatically:

Improved credit card security
Reduced in-store payment fraud

EMV technology has also allowed customers to use their cards abroad with greater convenience and confidence.

What are EMV credit cards, and how do they protect businesses and consumers from payment fraud?

The Basics: What Does EMV Stand for?

Short for “Europay, Mastercard, and Visa,” EMV credit cards come with embedded “smart chips” that offer much greater protection against fraud than their traditional magnetic stripe counterparts.

How Does EMV Chip Technology Help with Payment Security?

The embedded security chips that come with EMV technology are very difficult to clone. To successfully complete an in-store transaction at an EMV-enabled card terminal, the original version of the card (and chip) must be physically present.

Most of the world had already graduated to EMV chip technology by the time it arrived stateside in 2011. Yet, to speed the transition to this more secure payment standard, the U.S. introduced new liability rules in October 2015. Merchants and card-issuing banks that didn’t make the switch to EMV technology would be responsible for any losses resulting from fraudulent activity. They would also be subject to punitive fines.

As of 2019, more than one billion chip cards have been issued to U.S. consumers.1

How Does EMV Technology Work?

EMV chip technology can store far more information than magnetic stripe credit cards. This technology allows these credit cards to hold encrypted data, which helps protect against in-store payment fraud. Better still, this encrypted data is dynamic, meaning the information can change over time.

Whenever EMV chip technology is used for an in-store payment:

The customer “dips” his or her plastic into a chip reader at the point-of-sale (POS) terminal
The EMV chip generates a unique transaction code that can never be used again (by anyone else)

These transaction codes prevent EMV credit cards from being compromised. Even if they fall into the wrong hands, fraudulent cards are unable to generate the proper codes.

Because the rest of the world has already adopted EMV chip technology, Americans who still rely on legacy plastic often face difficulties when they shop abroad. However, using EMV cards helps to remove restrictions when buying in-person from merchants around the globe.

Why EMV Chip Technology Continues to Rise

Many stateside businesses continue to move to the more secure EMV chip standard. As of 2019, over 3.7 million merchants now accept chip cards.2

Here’s why:

EMV chip technology is inherently more secure than legacy credit cards. Instead of swiping a cloneable magnetic stripe at the point of sale, EMV cards must be dipped into or waved across a dedicated chip reader. Because these security chips are so hard to copy, in-person purchases benefit from much greater fraud protection
With liability rules in place, card-issuing banks and merchants are both incentivized to make the transition to more secure EMV technology. Failure to do so exposes them to exorbitant fines if payment fraud occurs
Most new EMV cards and chip-based readers come with near field communication (NFC) technology that allows for contactless payments. Rather than physically swipe plastic at the terminal, customers can simply wave their plastic across the reader – resulting in faster (and more secure) transactions

Although liability rules might be the driving force behind widespread EMV adoption, the transition is greatly aided by EMV chip technology’s enhanced security, greater speed, and unmatched convenience. Chip-enabled plastic is also the default payment standard for in-person transactions around the globe. This means that terminal manufacturers, card-issuing banks, merchants, and customers who haven’t already made the switch risk being cut out of the “sales” process.

What Equipment Is Needed to Accept EMV Chip Cards for In-Store Payments?

Getting started with EMV technology is a lot easier than most people realize.

As a consumer, all you need is a credit card embedded with an EMV security chip. Because most card-issuing banks ship EMV plastic due to the new liability rules, the majority of customers nationwide carry chip cards in their wallets.

As a brick-and-mortar merchant, you need a credit card machine that can correctly read EMV chip technology. However, this doesn’t mean investing in multiple terminals:

Nearly all EMV readers come with a magnetic stripe slot for payments made via legacy plastic
Most EMV terminals now come with NFC technology for contactless payments. This allows merchants to securely accept wireless payments made using EMV plastic or mobile wallets with stored credit card data

Even better, you don’t need to invest in a dedicated POS terminal to start accepting EMV payments. Clover Go, for example, allows merchants to turn their existing smartphones and tablets into portable credit card readers that can securely process payments made via contactless or EMV chip technology.

Does EMV Technology Affect Online Payments?

If you’re an eCommerce merchant, you can continue using your current payment gateway with no additional changes to your checkout flow. This is because there is no distinction between legacy plastic and EMV credit cards when shopping online. In both cases, customers initiate card-not-present (CNP) transactions that don’t require magnetic stripes or embedded security chips.

To ensure all of your online sales benefit from the ultimate in fraud protection, implement best practices to secure your eCommerce website.

A Brief History of U.S. EMV Technology Adoption

EMV chip technology is more secure than magstripe plastic. Still, making the shift to EMV payments proved to be very expensive for small businesses that couldn’t afford the necessary hardware upgrades to their POS systems.

In an effort to facilitate EMV technology adoption, fraud liability rules were altered in 2015 by U.S. credit card issuers:

Mastercard
Visa
Discover
American Express

After October 1, 2015, liability for in-store counterfeit fraud shifted to whichever side of a transaction wasn’t EMV-ready – either the merchant or the card-issuing bank. As such, non-compliance with EMV chip technology became more expensive than upgrading one’s payment environment. Adoption of the more secure standard began to go mainstream in the U.S.
