Magnetic Stripe Card
Magnetic Stripe Card
A magnetic stripe card (also known as a swipe card) is a type of payment card that stores magnetic data on a thin strip on the back of the card. This magnetic data is used to authenticate the card holder and authorize transactions.
Components:
- Magnetic stripe: A thin strip of magnetic metal on the back of the card that stores the magnetic data.
- Track data: The magnetic data stored on the stripe, which includes the card number, expiration date, and other security information.
- EMV chip: Some magnetic stripe cards have an embedded EMV chip that adds an extra layer of security.
Magnetic Data:
The magnetic data stored on a magnetic stripe card is typically encoded in three tracks:
- Track 1: Contains the card number, expiration date, and other primary account information.
- Track 2: Stores additional information, such as the cardholder’s name, address, and other loyalty program information.
- Track 3: Is a spare track that can store additional data, such as the card’s security code or PIN.
Security:
Magnetic stripe cards use magnetic secure strip (MSS) technology to protect the magnetic data from being copied or tampered with. MSS protects the data by encrypting it with a random number called the Card Verification Value (CVV) and a unique card number called the Account Number Verification Value (ANVV).
Uses:
Magnetic stripe cards are commonly used for making purchases at merchants that accept swipe cards. They are also used for electronic toll payments, ATM withdrawals, and other financial transactions.
Advantages:
- Convenience: Magnetic stripe cards are easy to use and convenient to carry.
- Security: MSS technology provides a high level of security against fraud.
- Compatibility: Magnetic stripe cards are widely accepted at merchants around the world.
Disadvantages:
- Fraud risk: Magnetic stripe cards are vulnerable to fraud if the magnetic data is stolen.
- Security breaches: Magnetic stripe cards can be compromised if the card reader is compromised.
- Manual data entry: Some magnetic stripe cards require manual data entry, which can be inconvenient.
