Through-the-Wall ATM Cash Dispenser for Secure Cash Withdrawal

KER Through-the-Wall ATM Cash Dispenser is a self-service banking terminal designed primarily for secure cash withdrawal services.

The machine is installed through a wall, with the customer-facing interface exposed on the front side while the cash safe, dispensing modules, computer and maintenance area remain protected inside the bank, service room or secure building area.

This installation method improves equipment security, simplifies cash replenishment and maintenance, and allows the ATM to provide convenient withdrawal services in bank branches, shopping centers, transportation hubs, commercial buildings and other public locations.

The machine can be customized with different cash dispensing modules, card readers, encrypted PIN pads, printers, cameras and communication systems according to the target banking platform and deployment environment.

Through-the-Wall Installation

The ATM is designed to be installed into a building wall or secure partition.

The customer uses the front panel to complete the transaction, while authorized staff access the cash safe and internal modules from the protected rear side.

Key benefits include:

• Separate customer and maintenance areas
• Improved cash and equipment security
• Convenient cash replenishment from a secure room
• Reduced exposure of internal components
• Suitable for bank lobbies and exterior wall installation

The final wall opening and installation structure can be customized according to the project site.

Self-Service Cash Withdrawal

The ATM can support a standard cash withdrawal process after integration with the customer’s ATM host, switch or banking platform.

A typical transaction may include:
