Credit card machines are indispensable tools for modern businesses, enabling the swift and secure processing of electronic payments. These devices act as a crucial link between a customer's payment card, the merchant, and the financial institutions involved, ensuring that funds are transferred efficiently and safely. Understanding how these machines work, their various types, and proper maintenance can help businesses optimize their payment processing.
A Brief History of Credit Card Machines
The concept of credit cards first emerged in the U.S. in the 1920s, primarily to facilitate fuel purchases for automobile users on long journeys, eliminating the need to carry large amounts of cash. Within a decade, their popularity grew as transactions became simplified, and a common understanding between financial institutions allowed for broader acceptance.
The idea of using multiple cards and making payments to various merchants became widespread in the 1950s. Today, countless types of credit cards exist, made from diverse materials and utilizing complex technologies to enhance security and convenience.
How Do Credit Card Machines Work?
Initially, credit card machines were designed solely for processing credit cards. However, modern devices often offer multifunctionality, capable of processing various card types. A typical credit card machine completes payment processing within seconds. It serves as an electronic means of exchanging information between the financial institution that issued the card and the payment-processing network.
When a customer makes a purchase and chooses to pay by credit card, the payment data is encrypted using Secure Socket Layers (SSL) for security purposes. This encrypted data is then sent to a payment gateway server, which forwards it to the relevant financial institution for validation. The institution analyzes the customer's credit details and sends an authorization message back through the gateway to the storefront, either accepting or rejecting the transaction. This real-time payment processing ensures that funds are transferred into the merchant's account according to the terms set by the credit card issuing agency.
What Are the Different Types of Credit Card Machines?
Credit card machines are generally categorized into four main types, each suited for different business needs:
- All-in-one credit card machine
- Standalone credit card machine
- Handheld credit card terminal
- Wireless credit card terminal
The all-in-one credit card machine is ideal for new businesses. It typically includes a built-in printer and supports all major payment types, including credit cards, debit cards, and check guarantees.
A standalone credit card machine is a suitable solution for processing phone and mail orders. It is user-friendly and generally does not require special software or an internet connection. Most standalone machines feature built-in printers for quick receipt generation.
The handheld credit card terminal is perfect for merchants and busy professionals who need mobility. It provides instant information about the availability of funds in a customer's account. Widely used in the food-service industry, these terminals are a significant advantage for hotel staff who are constantly moving to take orders, eliminating frequent trips to a fixed terminal to check card balances.
The wireless credit card terminal is commonly used by sales executives and others who spend little time in their offices. This terminal allows them to complete sales without needing a telephone line, offering the flexibility to conduct business virtually anywhere.
Understanding Credit Card Machine Components
A typical credit card machine consists of several key parts that work together to process transactions:
- Printer: Used to print transaction and batch receipts. Printers can be thermal, impact, or ink-based. Thermal printers use heat to create images on special thermal paper, while impact printers use carbon paper. Ink printers use ribbons or cartridges, similar to computer printers.
- Printer Paper: Specific types of paper are required depending on the printer technology (thermal, impact, or ink).
- Display: Shows details of the current transaction or function.
- Keypad: Used for manually entering transaction details and managing machine functions.
- Soft Keys: Pre-programmed keys that perform specific functions like programming, batching, returning items, or voiding transactions.
- Magnetic Card Reader: Captures information stored on the magnetic strip of a credit card. Different types of readers can read various tracks of data on the magnetic strip.
- Smart Card Reader: Processes cards embedded with a smart chip, offering enhanced security.
- Ports: Commonly RS232, but other sizes are also used to connect peripherals like printers, PIN pads, and external smart card readers.
- Power Plug: Provides power to the terminal via an AC adapter. Some terminals offer dual power options, allowing operation from both AC power and batteries in case of a power outage. Portable machines typically run on battery power.
- Phone Jack: Connects the terminal to a phone line, enabling it to dial the processing network and process transactions.
Tips for Maintaining Your Credit Card Machine
Like all electronic equipment, credit card machines perform better and last longer with proper care and timely maintenance. All operators in a business should be thoroughly trained to handle the machine carefully.
A common issue with electronic devices is reduced efficiency due to dust and foreign particle accumulation on circuit boards. Using protective, dust-proof covers can help mitigate this problem. However, dust and dirt can still enter, especially in non-air-conditioned environments. Machines should be periodically serviced by professionals to analyze the functioning of various parts and ensure there are no component defects.
Who Are the Major Credit Card Machine Manufacturers?
The market for credit card machines offers a wide range of options from various manufacturers. Some popular brands include Verifone, Hypercom, Lipman Nurit, Way Systems Inc, Thales, LinkPoint, PC Charge, Authorize.Net, ChargeMax PC, and Icverify.
Verifone and Lipman Nurit are notable for offering a broad selection of models, with many devices combining multiple functions into a single machine. Businesses can choose from terminals with or without built-in printers, wireless terminals, and options for electronic check processing, allowing them to select a device that perfectly fits their operational needs.
