This transition from magnetic stripe cards to EMV chip cards is reshaping the payment landscape, making it essential for businesses to understand the benefits and challenges of each technology to ensure secure transactions and meet customer expectations.
Understanding Magnetic Stripe Cards
A magnetic stripe card is a plastic card equipped with a magnetic strip that contains three horizontal tracks of data. This data includes essential information such as the cardholder’s name, account number, card balance, service code, and card verification value for point-of-sale (POS) transactions.
The magnetic stripe technology was pioneered in the 1960s by IBM engineer Forrest Parry, who developed it while designing secure identity cards for CIA officials. After some initial challenges, his wife suggested using an iron to melt the stripe onto the card, leading to its successful implementation. In 1969, American Airlines, American Express, and IBM introduced the first plastic credit card with a magnetic stripe—the American Airlines Air Travel Card.
This innovation revolutionized payment processing, enabling quick and convenient transactions primarily for credit and debit cards. Over the years, its applications have expanded to include driver’s licenses, government IDs, employee badges, hotel room keys, gift cards, and loyalty cards.
How Magnetic Stripe Card Transactions Work
When a magnetic stripe card is swiped through a card reader, the following sequence of events occurs:
- Data Extraction: The card reader retrieves the data encoded on the magnetic stripe.
- Authorization Request: The terminal sends an authorization request to both the acquiring and issuing banks.
- Verification: The issuer checks details such as available funds and the card’s expiration date to either approve or decline the transaction.
- Authorization Completion: The terminal facilitates the authorizations between the issuing bank and the acquiring bank.
- Transaction Finalization: Once all authorizations are received, the cardholder signs the receipt, completing the transaction.
What is an EMV Chip Card?
EMV chip cards incorporate a microprocessor chip that securely processes transactions and offers enhanced protection against fraud. EMV stands for Europay, Mastercard, and Visa, the credit card companies responsible for the development of this technology. Today, the standard is overseen by EMVCo, a consortium that includes Visa, Mastercard, JCB, American Express, China UnionPay, and Discover.
While the first chip cards were introduced in France during the 1960s, widespread adoption faced challenges due to compatibility issues with payment terminals. In the 1990s, the EMV global standard was established to ensure consistent, interoperable use across the globe.
The adoption of EMV technology surged as security concerns and data breaches became more prevalent. The chip’s encryption capabilities provide superior fraud protection, establishing it as the global standard for secure card transactions.
How EMV Chip Card Transactions Work
Transactions involving EMV chip cards at point-of-sale terminals follow these steps:
- Card Insertion: The card is inserted into the terminal, where the terminal’s pins make contact with the chip.
- Chip Activation: The chip is activated, and the terminal verifies the issuer’s details stored within it.
- PIN Authentication: The chip authenticates the PIN entered by the cardholder.
- Transaction Signing: The terminal utilizes the chip’s public key to digitally sign the transaction.
- Authorization Submission: The transaction details are sent to the bank for authorization.
- Transaction Completion: Once authorized, the transaction is finalized.
Comparing Magnetic Stripe Cards and EMV Chip Cards
Magnetic stripe cards and EMV chip cards differ significantly in several crucial areas.
Security
- Magnetic Stripe: These cards are susceptible to skimming, card cloning, and data theft during card-present transactions. The static data on magnetic stripes can be easily copied using low-cost skimming devices, leading to credit card fraud and the creation of counterfeit cards.
- EMV Chip: EMV chip cards enhance security by encrypting data and generating a unique code for each transaction, making replay attacks nearly impossible. This dynamic data makes it exceedingly difficult for fraudsters to reuse stolen information.
