How Credit Card Swipers Work: A Comprehensive Guide

Credit card swipers are a common sight in stores, restaurants, and other businesses. They work by allowing customers to swipe their credit or debit card through a reader, which then processes the payment and sends it to the merchant’s bank account. The technology behind credit card swipers is based on magnetic stripe technology, which has been widely used in the banking industry since the 1960s. In this article, we’ll explore the inner workings of credit card swipers, how they process payments, and the security measures that are in place to protect consumers and merchants.

Understanding the Components of a Credit Card Reader

Credit card readers or swipers, are devices that are commonly used in modern-day retail businesses. They are designed to read the information stored on credit cards and facilitate transactions. To understand how credit card readers work, it is essential to get familiar with the components and mechanics of the device.

The Magnetic Stripe

The magnetic stripe is the black strip on the back of a credit or debit card that stores the card’s personal information. The magnetic stripes are made up of tiny iron-based magnetic particles that are arranged in a specific sequence. The magnetic stripe contains three tracks and different information on each track.

The Card Slot

The card slot is the area of the credit card reader where the magnetic stripe of a card is inserted for reading. The card slot is designed to read the stripe when it’s swiped through, and it does so by detecting and reading the magnetic signals through the card’s magnetic stripe.

The Reader Head

The reader head is the component of a credit card reader responsible for reading the card’s magnetic stripe. It’s a small device located inside the card reader, and it reads the information from the magnetic stripe on the card.

The Control Board

The control board is the “brain” of a credit card reader, and it’s responsible for processing the data read from the magnetic stripe. The control board uses software to interpret the magnetic signals and convert them into usable data.

The Wires

The wires connect the different components of the credit card reader. The wires are essential as they transmit the data signals from the reader head to the control board for processing.

The Microprocessor

The microprocessor is the chip that controls the functions of a credit card reader. It’s responsible for processing the data from the control board and transferring it to the POS system of the merchant.

Power Supply

The power supply is responsible for powering the credit card reader. It’s connected to the power source and ensures that the credit card reader is always functioning.

Signal Amplifier

A signal amplifier strengthens the signal from the magnetic stripe during the reading process. The amplifier amplifies the magnetic signal to compensate for any interference that may occur during the reading process.

The Screen and Keypad

Many credit card readers have screens and keypads that allow merchants to input data, view sales, and track transactions. These features are essential as they facilitate easy operation and help merchants keep track of their transactions.

Connectivity

The connectivity feature allows the credit card reader to communicate with the merchant’s POS (point of sale) system, allowing for a seamless transaction process. The connectivity allows for instantaneous transfer of data between the credit card reader and the POS system.

In conclusion, modern credit card readers use powerful hardware, sophisticated software and connectivity to ensure seamless transactions. Understanding the components and mechanics of credit card readers allows you to appreciate the complexity and importance of these devices.

Magnetic Strip Credit Cards

Magnetic strip credit cards are the most common type of credit card used today. This type of credit card works by using a magnetic strip that contains all the necessary information needed to process a transaction. The strip is located on the back of the card and looks like a thin black bar.

How Does the Magnetic Strip Work?

The magnetic strip on a credit card contains tiny particles of magnetic material that are arranged in a specific pattern. When the card is swiped through a card reader, the magnetic strip is read by a magnetic head that is located inside the card reader. This head reads the pattern of the magnetic particles on the strip and uses this information to decode the data that is stored on the card.

The Data Stored on the Magnetic Strip

The data that is stored on the magnetic strip of a credit card includes the cardholder’s name, credit card number, expiration date, and security code. This information is used to verify that the card is valid and that the transaction can be processed.

How Does the Reader Get the Data?

Once the magnetic strip has been read, the data is transmitted to the card reader’s processor, usually via a wired or wireless connection. The processor then checks the data against the cardholder’s account details to ensure that the transaction can be approved.

Chip-and-PIN Credit Cards

Chip-and-PIN credit cards are a more recent addition to the credit card market. These cards use an embedded microchip and require the user to enter a PIN (Personal Identification Number) to verify that they are the rightful owner of the card.

How Do the Chips Work?

The chip on a chip-and-PIN card contains a secure microprocessor that stores the cardholder’s account details. When the card is inserted into a chip-and-PIN reader, the microprocessor sends a unique code to the reader that can only be decoded using the correct PIN.

Benefits of Chip-and-PIN Cards

Chip-and-PIN cards are considered to be more secure than magnetic strip cards because they are harder to clone or skim. Skimming is the practice of stealing credit card information by scanning the magnetic strip, while cloning involves copying the magnetic data onto a fake card.

Contactless Credit Cards

Contactless credit cards are a type of chip-and-PIN card that allow users to make payments by simply tapping their card on a contactless card reader. These cards are designed to make payments faster and easier by eliminating the need to enter a PIN or sign a receipt.

How Do Contactless Cards Work?

Contactless cards use a tiny antenna that communicates with a contactless card reader when the card is held close to the reader. The antenna creates an electromagnetic field that powers the card and allows it to transmit the data needed to complete the transaction.

Benefits of Contactless Cards

Contactless cards are faster and more convenient than traditional chip-and-PIN cards, as they eliminate the need to enter a PIN or sign a receipt. They are also more secure than magnetic strip cards, as they require the user to be in close proximity to the card reader in order to make a payment.
