What Is a Magnetic Stripe Reader?

A magnetic stripe reader is an electronic device that uses magnetic reading technology to read information stored on the magnetic stripe of a card or similar object. The magnetic stripe is a thin strip of magnetic material found on the back of credit cards, debit cards, identification cards, and other items that use this data storage technology.

MSRs are used for data management in many industries, from banking and finance to transportation and security. In addition, there are different types of MSRs, which adapt to the specific needs of each sector.

History Of the MSR

The development of the magnetic stripe reader dates back to the 1950s, when researchers began experimenting with magnetic technology for data storage. In 1960, IBM introduced the first magnetic stripe credit card system, which allowed the electronic transmission of data between merchants and card-issuing banks.

The use of the magnetic stripe quickly became popular, and in the following decades, MSRs were developed and improved. In the early 1970s, magnetic stripe technology expanded into other applications, such as employee ID cards and facility access cards.

As digital technology advanced, the magnetic stripe’s ability to store large amounts of information became a major advantage. In the 1980s, MSRs capable of reading multi-track information from the magnetic stripe were developed, allowing greater storage capacity and greater security in data transmission.

Today, MSRs are widely used around the world in a variety of applications, from credit and debit cards to transportation and ID cards, and continue to be an important tool for data management.

How Does a Magnetic Stripe Reader Work?

A magnetic stripe reader works by using a magnetic read head to read the information encoded on the magnetic stripe of a card or other object. The magnetic stripe is a thin strip of magnetic material that contains tracks of encoded information.

As the card is swiped through the MSR, the magnetic read head detects the variations in the magnetic field generated by the information tracks on the magnetic stripe. The MSR then converts these variations into electrical signals that are processed by a software or data management system to decode and use the information stored on the magnetic stripe.

Information stored on the magnetic stripe may include account numbers, cardholder names, expiration dates, and transaction history, among other data. A magnetic stripe reader can also verify the authenticity of the card and the validity of the information on it.

It should be noted that the use of magnetic fields to store and read information on cards can be affected by external factors, such as the presence of strong magnetic fields or exposure to temperature or humidity. Therefore, it is important to keep the cards and MSRs in good condition to ensure that they function properly.

Uses Of an MSR

MSRs have a wide variety of uses in different sectors.

  • Banking and finance: they are used to read and process information from credit and debit cards and other electronic means of payment.
  • Transportation: Public transportation systems use magnetic stripe cards to pay ticket prices and to control access to stations and vehicles.
  • Identification: MSRs are used to read information from employee and visitor identification cards, as well as in security checkpoints and access control systems.
  • Health: They are also used in electronic medical record systems to access patient information.
  • Entertainment: They are used for access control to events, such as concerts and festivals, as well as in the membership card systems of clubs and casinos.
  • Security: MSRs are used in building access control systems and facility security systems, such as access control systems at airports.

Types Of MSRs

There are several types of MARs, each with specific characteristics that make them suitable for different applications.

  • MSR: This type of reader is used to read information from a magnetic stripe card by manually swiping the card through the reader. They are portable and commonly used in restaurants and retail stores.
  • Embedded MSR: Embedded in another device, such as a point-of-sale (POS) terminal, ATM, or vending machine. They are common in the financial services industry, public transportation, and facility access.
  • Desktop MSR: This is larger and designed for use on a desktop workstation. They are common in the credit and debit card, and financial services industry.
  • Smart Card MSR: Has the ability to read both magnetic stripe and smart card information. They are commonly used in security and access control applications.
  • MSR for mobile phones: This type of reader connects to a mobile phone and allows the reading of the information on the magnetic stripe of the cards. They are common in the mobile payment industry.

Advantages And Disadvantages of a Magnetic Stripe Reader

A magnetic stripe reader has several advantages and disadvantages that must be considered when choosing it for a given application. Here are some of the most common MSR advantages and disadvantages:

  • Advantages:

Magnetic stripe technology has been widely accepted and used for decades, which means that most cards and other devices that contain magnetic stripe information can be read by most MSRs.

MSRs are generally less expensive than other types of reading technologies, making them affordable for a wide variety of applications.

Additionally, they are easy to use and do not require special training skills. Magnetic strips are strong and durable, which means that the information on them can be read many times before they wear out.

  • Disadvantages:

Magnetic stripe information can easily be copied or cloned, making it vulnerable to fraud. Magnetic stripe technology does not offer the same level of security as other reading technologies, which can be a problem in applications that require higher levels of security.

The amount of information that can be stored on a magnetic stripe is limited compared to other data storage technologies.

On the other hand, the magnetic stripe is sensitive to dirt, which can cause reading errors.

Access To Buildings

MSRs are commonly used in building access control, where users are required to present a card or badge to enter a restricted area. In this case, the magnetic stripe reader is connected to an access control system that verifies the information contained in the magnetic stripe of the card or the user’s credential.

When the user presents their card or credential to the MSR, it reads the information encoded on the magnetic stripe and sends it to the access control system for verification. If the information is correct and the user is allowed to access the restricted area, the access control system will send a signal to the MSR to allow the user entry. Otherwise, they will be denied access.

In some cases, the same access control system that verifies the user’s card or credential information through the MSR may be connected to the building’s door-opening system. In this case, after the access control system verifies the user’s information, it sends a signal to the door opening system to unlock the main door or the access door to the restricted area.

However, it is important to note that the exact configuration of the access control system varies depending on the design and functionality of the building. In some cases, the door opener may be connected to a separate access control system and may use different reading technologies, such as smart card technology, instead of a magnetic stripe.

In either case, the purpose of the access control system is to allow only authorized users access to restricted areas, thereby increasing the security and protection of building assets and the people who work or live there.
