Inside a GRG ATM: Understanding Its Key Components
ATMs (Automated Teller Machines) have revolutionized the way we access banking services. From cash withdrawals to deposits and more, these machines allow 24/7 self-service transactions. One of the global leaders in ATM technology is GRG Banking, known for its innovation, reliability, and secure hardware. But what exactly is inside a GRG ATM? What makes it work so efficiently? Let’s take a closer look at the main components of a GRG ATM and their functions.
Card Reader
The card reader is where every transaction begins. It identifies and authenticates your bank card—whether it has a magnetic stripe, EMV chip, or contactless (NFC) capability. GRG machines are equipped with high-precision readers that ensure safe and fast card detection, minimizing reading errors.
Encrypted PIN Pad
The PIN pad is the keypad used to enter your personal identification number. GRG’s encrypted PIN pads comply with PCI-DSS standards and are protected against tampering. Some machines also offer on-screen PIN entry as an added security option.
Cash Dispenser Unit
This is the part of the machine that delivers your money. GRG’s cash dispenser modules are built to handle multiple denominations with high accuracy. They include sensors to detect counterfeit notes, and if a note cannot be dispensed properly, it’s sent to a reject bin for safety.
Cash Deposit / Recycler
Many GRG ATMs are equipped with cash deposit or recycler units. When users deposit money, these modules validate the notes and store them for future withdrawals—reducing the need for frequent cash refills. This improves efficiency and lowers operational costs for banks.
Touchscreen Display
GRG ATMs feature high-resolution touchscreens that guide users through each step of a transaction. They often support multiple languages and have a user-friendly interface. Screens are built to be durable, weather-resistant, and easy to read even in sunlight.
Receipt Printer
After a transaction, the ATM prints a summary using a thermal receipt printer. GRG’s printers are fast, quiet, and include automatic paper cutters. When paper is low or jammed, maintenance alerts are triggered instantly.
Safe
The ATM safe is the most secure part of the machine. It stores cash and protects internal components. GRG safes are made of reinforced steel and are equipped with advanced locks, vibration sensors, and fireproof materials for maximum protection.
PC Core (Main Processing Unit)
The PC Core is the central brain of the ATM. It connects with the bank’s systems, manages hardware, processes user input, and ensures all transactions are completed correctly. Software updates and security features are also controlled here.
Communication Module
To perform real-time banking, GRG ATMs use a communication module that connects to banking networks via 4G, Ethernet, or VPN. This ensures secure data transfer between the ATM and the financial institution.
Security Features
GRG ATMs come with a wide range of security measures:
- Built-in cameras
- Anti-skimming devices
- Tamper and shock sensors
- Intrusion detection alarms
These features help protect the machine and users from fraud or physical attacks.
