🏧 All About ATMs: Definition, History, and How They Work
The ATM, or Automated Teller Machine, is an electro-mechanical marvel that has transformed banking by offering self-service platforms. These devices empower users to perform banking tasks without requiring a branch representative or teller. Whether withdrawing cash, transferring funds, or checking account balances, ATMs have become an essential part of modern financial systems. Let's dive deeper into their workings, history, and significance!
🤔 What Is an ATM?
An ATM (Automated Teller Machine) is a banking kiosk designed to perform a variety of transactions such as:
- 🏧 Cash withdrawals
- 💳 Deposits
- 📄 Balance inquiries
- 🔄 Account-to-account transfers
ATM users typically need a debit or credit card to access these services. A Personal Identification Number (PIN) ensures secure access. While fees may be charged for withdrawals, these can often be avoided by using ATMs operated by the bank associated with your account.
ATMs are recognized globally by various names, such as ABM (Automated Bank Machines) or simply Cash Machines.
