How Do ATM Machines Work—and Why Businesses Should Care
Most people use ATMs regularly, but few stop to consider how these machines actually work behind the scenes. Whether it’s a quick cash withdrawal or a balance inquiry, ATMs perform secure transactions in seconds. For businesses, understanding how ATM machines work opens the door to new revenue streams, improved customer convenience, and added foot traffic.
ATMs are more than banking tools—they’re business opportunities. At Boston North Company, we help businesses across New England take advantage of ATM services that benefit both the customer and the bottom line. Let’s learn more about how these machines work.
What Happens When You Use an ATM?
When someone walks up to an automated teller machine (ATM) to withdraw cash, a precise process kicks into motion. First, the customer inserts a debit card or credit card into the machine’s card reader. Then, they enter their personal identification number (PIN) to access their bank account securely.
Once the PIN is verified, the customer chooses a transaction—typically a cash withdrawal, balance inquiry, or transfer. The ATM connects to the bank’s system via a secure network ATM, checks the account balance, and confirms the request.
If approved, the cash dispenser inside the ATM calculates and releases the exact amount of cash requested. Within moments, the customer receives their money, a printed receipt, and updated account data—all without needing to interact with a bank teller. It’s this seamless, automated process that defines modern ATM convenience.
Key Components That Make ATMs Work
Every automated teller machine operates using several integrated components. Together, these pieces of hardware and software make ATM use simple and secure:
- Card Reader – Scans the magnetic stripe or chip on a debit card or credit card to begin the transaction.
- PIN Pad – Allows the user to enter their personal identification number (PIN) securely.
- Cash Dispenser – Dispenses the exact amount of cash requested during ATM transactions.
- Display Screen – Guides users step-by-step through their selected service.
- Receipt Printer – Issues a printed summary for record-keeping.
- Computer & Software System – Processes data and communicates with the banking network.
- Internal Vault – Secures large amounts of cash in a locked environment.
- Modem/Network Interface – Links the ATM to the financial institution’s servers through a network ATM connection.
Each of these components is essential to the reliable operation of automated banking machines, allowing users to interact with their bank account quickly and securely, 24/7.
Where ATMs Are Used—and Why That Matters to Businesses
ATMs aren’t just found at banks anymore—they’re commonly located in grocery stores, gas stations, convenience stores, salons, restaurants, bars, and other high-traffic areas. These automated teller machines allow customers to access funds anytime without needing a bank teller, creating a convenient experience.
For business owners, hosting an ATM is more than a courtesy—it’s a smart business move. Customers are more likely to make impulse purchases when they withdraw cash on-site, and many prefer having easy access to their account balance during shopping. Research shows that a significant portion of funds withdrawn from in-store ATMs—sometimes up to 30%—is spent at the same location.
Boston North Company offers a variety of ATM solutions that make implementation simple. With flexible placement options, revenue-sharing programs, and ongoing maintenance, adding an ATM to your business is easier than ever.

Why Understanding ATMs Helps Businesses Make Smarter Decisions
For business owners, knowing how ATM machines work can inform smart decisions about placement, usage, and profitability. Many business owners assume ATM ownership is complicated, but today’s systems are designed for low maintenance and high performance.
Boston North Company offers multiple program options. With full ownership, businesses can keep 100% of the surcharge revenue while controlling refills and maintenance. For those seeking a more hands-off approach, shared revenue or full-service models allow the business to provide ATM access without managing logistics.
Regardless of the model, the benefits remain clear. Automated teller machines attract foot traffic, improve the customer experience, and give cash-preferred shoppers a reason to stay and spend. Businesses also cut down on credit card processing fees and reduce the risk of card-only sales environments.
