Basics of Magnetic Stripe Card Readers
What Is a Magnetic Stripe Card Reader
A Magnetic Stripe Card Reader reads the black stripe on cards. This stripe has important details like account numbers or access rights. A magnetic stripe reader is a device that reads data on the stripe. The stripe is a layer of magnetic stuff on a plastic card. You cannot save or write new data with the reader. It only reads what is already on the card.
When you swipe your card, the reader gets the data from the stripe. People use these readers for credit cards, badges, or bus passes. The device helps you pay, open doors, or check in for trips. You see Magnetic Stripe Card Readers in many places. They make using cards fast and simple.
How It Works
You can learn how a Magnetic Stripe Card Reader works by looking at its steps. First, you swipe or insert your card. The card moves past a read head inside the reader. The read head senses changes in the magnetic field. It turns these changes into an electric signal.
The reader changes this signal into digital data. Then it sends the data to a computer or terminal. Next, the system checks the data in a database. If the data matches, you get access or your payment works.
Here is a simple list of the steps:
Swiping or Inserting the Card: You move the card through the reader.
Reading the Magnetic Data: The read head senses the magnetic changes.
Decoding and Transmitting the Data: The reader changes the signal into digital data and sends it to a system.
Authentication and Response: The system checks the data and gives you access or approves your payment.
Tip: You do not need special skills to use most Magnetic Stripe Card Readers. Many models work with a simple swipe or insert, making them user-friendly.
You may wonder what kind of data the reader gets from your card. The magnetic stripe has three tracks. Each track keeps different information. The table below shows what each track does:
Track Number | Function Description |
|---|---|
Track 1 | Holds letters and numbers, mostly for money transactions. |
Track 2 | Holds numbers, often used in banks and security. |
Track 3 | Holds extra security details, but is not used much. |
You use these tracks every time you swipe your card. The reader gets the right data for your payment or access.
Types of Magnetic Stripe Reader
Interface Types: USB, RS232, and TTL
You can connect magnetic stripe card readers to computers and other devices in different ways. The most common interfaces are USB, RS232, and TTL. Each type has its own strengths.

|---|---|---|
USB | Plug-and-play, easy to use, works with most computers, no extra software needed | Retail stores, offices, schools |
RS232 | Good for older systems, stable connection, often used in industrial settings | Kiosks, gaming machines, petrol stations |

By Card Type (Magnetic Stripe Type)
Magnetic stripe cards come in two main types: Low-Coercivity (LoCo) and High-Coercivity (HiCo). The type you choose depends on how you plan to use the card.
Type | Coercivity (Oe) | Appearance | Durability | Typical Uses |
|---|---|---|---|---|
LoCo | 0 – 300 | Brown Stripe | Easier to erase, less durable | Hotel keys, transit passes, gift cards |
HiCo | 300 – 3000 | Black Stripe | Harder to erase, more durable | Credit cards, employee IDs, access cards |
LoCo cards low coercivity magnetic stripes are easy to write and erase. You find them in hotels and transit systems. These cards work well for short-term use.
HiCo cards high coercivity magnetic stripes store more data and resist wear. You use them for bank cards and employee badges. These cards last longer and keep your data safe.
Note: HiCo cards need a stronger magnetic field to write data. This makes them better for cards you use every day.
