What it means
Older cards stored the same fixed data on a magnetic stripe, which could be copied and used to make counterfeit cards. EMV cards contain a small computer chip that creates a unique code for every transaction.
A copied code is useless for the next purchase because it will not match. When a customer inserts or taps an EMV card, the chip and the terminal exchange information to confirm that the card is genuine.
The cardholder may also be asked to enter a PIN (a personal identification number) or sign, depending on the card and the transaction. Contactless payments use the same technology over a short-range wireless link.
For businesses, the practical effect is a shift in who pays when fraud happens. In some regions, if a merchant does not have an EMV-capable terminal and a counterfeit card is used, the merchant can be held responsible for the loss.
This is called a liability shift, and it gave retailers a strong reason to upgrade their equipment. Finance teams should factor EMV into payment costs and risk planning.
That means budgeting for terminals, ensuring staff are trained, and reviewing chargebacks, which are the reversals of card payments after a dispute. Compliance with card industry security rules also remains important because EMV does not protect every kind of payment.
An important nuance is that EMV reduces fraud when the card is physically present, but it does not stop online fraud. Card-not-present payments, such as those made on a website, need other protections like tokenisation and extra authentication.
In some contexts the letters can also mean expected monetary value, a decision analysis term, so check which meaning is intended.
In practice
Real-world examples.
Example
A clothing retailer replaces its old card readers with EMV terminals in all 12 stores. Counterfeit card fraud in the stores drops sharply within a year. The finance team records the equipment as an asset and depreciates it over several years.
Example
A restaurant owner receives a chargeback for a $300 dinner because a counterfeit card was swiped on an old terminal. The card issuer places the loss on the restaurant under the liability shift rules. The owner decides to upgrade the terminal the same week.
Example
A ride-sharing startup issues drivers with prepaid EMV cards for fuel. Each purchase is verified by the chip, which makes it harder for stolen card details to be reused. The finance team sees fewer disputed items during monthly reconciliation.
Formula
Calculation
Fraud loss = Number of fraudulent transactions x Average fraudulent transaction value
Suppose a shop without an EMV terminal suffers 40 counterfeit card transactions a year, averaging $150 each. Fraud loss = 40 x 150 = $6,000. After installing EMV terminals at a cost of $3,000, the number of counterfeit transactions falls to 5 a year. The new loss is 5 x 150 = $750, so the saving is 6,000 - 750 = $5,250 in the first year, which more than covers the cost of $3,000.Case study
Seen in the real world.
Greenfield Garden Centres is a fictional retail chain, used here only as an illustration. For years it used older terminals that read the magnetic stripe, and its finance manager noticed a steady rise in chargebacks from counterfeit cards. In one year the company lost about $45,000 from this type of fraud.
The manager presented a business case to upgrade all tills to EMV terminals at a total cost of $30,000. The following year, counterfeit losses fell to under $5,000, and the saving covered the investment within the first twelve months. Staff were also trained to spot signs of tampering with terminals. All details are fictional and illustrative.
The manager also set a routine for the future. Terminals are inspected every month, chargeback reports are reviewed by the finance team, and online sales now use extra authentication, because the chip does nothing for card-not-present payments. The board agreed that the programme should be treated as an ongoing control and not a one-off purchase. All details are fictional and illustrative.
Watch out
Common mistakes.
- Thinking EMV stops all card fraud, when online payments need separate safeguards.
- Delaying a terminal upgrade without realising that liability for counterfeit fraud may move to the merchant.
- Confusing EMV with contactless, when contactless is one way of using the EMV chip rather than a separate standard.
Questions
People also ask.
What does EMV stand for?
It stands for Europay, Mastercard and Visa, the three organisations that developed the standard.
Does EMV protect online purchases?
Not directly, because there is no chip present, so online payments rely on other methods such as tokenisation and extra authentication.
Who pays if fraud occurs?
It depends on the rules of the card scheme and region, but the party with the less secure technology often bears the loss.
