Magnetkaardid

Magnetkaardid, also known as magnetic cards, are a type of identification and payment card that use magnetic stripes to store data. These cards are widely used in various applications, including access control, payment systems, and identification purposes. The magnetic stripe on the back of the card contains encoded information that can be read by a magnetic card reader.

The magnetic stripe consists of three tracks, each capable of storing different types of data. Track 1 typically holds cardholder information such as the name, account number, and expiration date. Track 2 is used for the primary account number (PAN), which is the unique identifier for the card. Track 3 is less commonly used and can store additional information.

Magnetic cards are relatively inexpensive to produce and maintain, making them a cost-effective solution for many applications. However, they are more susceptible to data corruption and wear compared to more advanced technologies like EMV chips. Despite this, magnetic cards remain a popular choice due to their simplicity and reliability in many everyday transactions and access control systems.

The use of magnetic cards has declined in recent years with the advent of more secure technologies such as EMV chips and contactless payment methods. Nevertheless, they continue to be used in certain legacy systems and applications where their simplicity and cost-effectiveness are advantageous.
