Summarize with

The financial services industry is in the midst of its most dynamic transformation yet. Driven by digital acceleration, consumer expectations, regulatory pressure, and ongoing cost constraints, financial institutions are reimagining their entire self-service infrastructure.

Even as digital banking expands, self-service channels remain the essential bridge between the physical and digital experience – ensuring accessibility, maintaining trust, and providing reliable access to cash, which continues to be the world’s anchor of confidence.

In this shifting landscape, Diebold Nixdorf’s DN Series^® 300 & 350, powered by the DM7V dispensing module, emerges as a cornerstone of next-generation self-service technology. It’s not just another ATM, it’s a strategic enabler of digital-first banking, designed to help financial institutions scale smarter, serve better, and innovate faster.

Reinventing the Self-Service Equation

For decades, banks have faced a critical dilemma: how to elevate customer experience while simultaneously reducing operational costs. Historically, improving one came at the expense of the other. The DN Series 300 & 350 resolves this challenge with a modular, multifunction platform that unifies technology across ATMs, cash recyclers, and teller environments.

This unified platform allows institutions to streamline their infrastructure by standardizing components, reducing spare parts, and consolidating service models. Predictive analytics and AI-driven maintenance through DN AllConnect^® Services ensure maximum uptime, fewer field interventions, and lower total cost of ownership.

The result is a future-ready self-service network that operates leaner, performs better, and delivers consistent reliability across every consumer touchpoint. This transformation allows banks to focus on what truly matters: improving customer satisfaction and profitability.

Experience Redefined: From Transaction to Connection

In the modern banking world, user experience (UX) has become a competitive differentiator. Customers expect self-service interactions that are intuitive, fast, and secure, comparable to the seamless UX of digital apps. The DN Series 300 & 350 brings this vision to life with its consumer-first design philosophy.

The devices feature 15” and 19” angled displays, intelligent LED lighting, and voice-guided assistance to support accessibility and comfort. With Reach Assist software and full compliance with global accessibility standards (ADA, CAE, CEN, CSA), every customer can complete transactions confidently, regardless of ability.

Banks can also extend their brand presence through customizable fascias, lighting, and color schemes, turning every ATM into an extension of their digital identity. What was once a simple transaction point is now a dynamic brand experience, driving loyalty and trust.

Efficiency That Drives Profitability

Efficiency in self-service banking is no longer a back-office goal; it’s the foundation of sustainable profitability. The DN Series 300 & 350 redefines efficiency across every dimension, from cash handling to device certification.

Smarter Cash Management

Powered by the DM7V cash dispenser, the platform delivers superior note handling with up to 14,000-note capacity and support for eight denominations or multiple currencies. This high-capacity, compact design minimizes replenishment frequency and enables intelligent cash optimization, lowering operational costs and extending uptime across networks.

For banks in markets with diverse transaction patterns, e.g., urban, rural, or cross-border, the DN Series 300 & 350 adapts easily through configurable cassettes and predictive maintenance tools. This means greater operational flexibility and control over cash supply chains.

Certification, Service, and Sustainability

The standardized interfaces and multivendor compatibility built into the DN Series accelerate certification and deployment across geographies, reducing time-to-market for new banking services. Additionally, shared components across teller and ATM environments simplify maintenance and reduce spare part inventories.

This not only drives cost efficiency but also supports sustainability objectives by extending product lifecycles and minimizing electronic waste, a key part of ESG-driven banking transformation.

Security Engineered for a Connected World

As self-service channels grow more interconnected, the risk of cyber and physical attacks rises. Security, therefore, is not a feature, it’s an imperative. The DN Series^® 300 & 350 provides multi-layered protection across physical, logical, and transactional levels.

The new systems set a benchmark for security and resilience in high-risk environments. It incorporates ExGas-rated safes, anti-cash-trapping shutters, and explosion-deterrent designs to safeguard against physical attacks. Advanced sensors continuously monitor for abnormal behavior in real time, enabling proactive threat prevention.

At the core of data security, Trusted Device Communication (TDC) ensures every exchange is fully encrypted and authenticated. Powered by up End-to-End Authentication (E2E), TDC delivers unmatched protection for dispense transactions. Building on this robust foundation, the DM7V Dispenser module—driven by the DN AllConnect^® Data Engine (ACDE)—introduces a patent-pending, AI-enabled Anti-Jackpotting solution, adding yet another critical layer of defense against jackpotting and black-box attacks.

True to our spirit of innovation, DN pioneered the first patent-pending solution against EMV Relay attacks in the Banking Automation space. Continuing this industry-leading momentum, the DM7V module is designed with Post-Quantum Computing (PQC) readiness, ensuring resilience against future threats posed by quantum advancements.

The integration with Vynamic^®Security Suite ensures protection against sophisticated logical attacks such as jackpotting, host spoofing, and malware injections.
With DN300 and DN350, every interaction is protected, reinforcing customer trust in self-service channels as secure extensions of the bank’s digital ecosystem.

The Future of Self-Service: Unified, Intelligent, and Inclusive

Today’s financial institutions are navigating the rise of hybrid banking, where digital and physical channels coexist seamlessly. The DN Series 300 & 350 serves as the backbone of this hybrid model, merging teller, ATM, and cash recycler functions through shared architecture and unified management.

This convergence creates a harmonized ecosystem where every touchpoint - whether in-branch, off-site, or digital - is powered by consistent data, security, and user experience. For consumers, that means frictionless interactions. For banks, it means reduced silos, simplified operations, and scalable innovation.
