How do magnetic strip cards work?

A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head.

What is magnetic strip function?

A magnetic stripe card is a type of pass that permits the user to complete electronic transactions or access a locked physical space. Types of magnetic stripe cards currently in use include driver’s licenses, credit cards, employee ID cards, hotel rooms, gift cards, and public transit cards.

How does magnetic stripe protect information?

Magnetic-stripe cards are, well, magnetized. When you swipe them, the payment processor reads their magnetic fields and matches them to your bank account information. The problem with this is that the data is static, making it easier for fraudsters to lift your information and clone it onto a new card.

What is a disadvantage of using magnetic stripe cards for access control?

The magnetic stripe reader system also is not secure. The data usually is not encrypted as securely as “smart card” technologies that store much more data using a microchip inserted into the card. Readers that fall into the wrong hands can easily be manipulated to steal data from unsuspecting victims.

Do chip cards have a magnetic strip?

Today, every chip credit card you get in the U.S. will use Chip-and-Signature technology, in addition to having a magnetic stripe on the back. Some cards also include the Chip-and-PIN function, so they’re more compatible overseas and more secure in the U.S. There’s much more to EMV technology.

What do magnetic stripes look like?

Magnetic Stripes Some stripes have normal polarity and some have reversed polarity. These stripes surround the mid-ocean ridges. There is one long stripe with normal magnetism at the top of the ridge. Next to that stripe are two long stripes with reversed magnetism.

How CVV is calculated?

The Visa CVV Generate verb calculates a 1-byte to 5-byte value through the DES-encryption of the PAN, the card expiration date, and the service code using two data-encrypting keys or two MAC keys. The resulting double-length key meets a more recent industry standard of using TDES to support PIN-based transactions.

How does a mag stripe access control system work?

Featuring ​encoded magnetic stripe technology, mag stripe access control systems work with ​mag swipe technology readers and low coercivity (LoCo) and high coercivity (HiCo) mag cards. Many organizations utilize ​mag stripe​ technology to make photo ID badges for uses ranging from door access and parking to cafeteria meals and book checkouts.

How does a magnetic stripe card reader work?

A magnetic stripe card reader can read either type of magnetic stripe. When magnetic stripes are encoded, a unique serial number is stored on the strip. This serial number is recognized by the POS system or access control lock device, providing access to funds stored on the POS system or opening a locked door.

What do you need to know about magnetic stripes?

Understanding magnetic stripe cards. Order magnetic stripe cards. Magnetic stripes or mag stripes, are the dark strip of magnetic material often seen on the back of gift cards , loyalty cards and membership cards, which are used in conjunction with a POS system. Mag stripe cards are also used in access control as key cards,…

How does a swipe card access control system work?

Magnetic (mag) stripe card access control — also known as swipe card access control — is a low security controlled access solution. Featuring ​encoded magnetic stripe technology, mag stripe access control systems work with ​mag swipe technology readers and low coercivity (LoCo) and high coercivity (HiCo) mag cards.
