What if paying for travel could feel so effortless and natural that people barely noticed it happening?
This question set the tone for a discussion on digital wallets and the long journey that has taken transport systems from plastic cards to phones, watches, and cloud‑based credentials. Paul Monk, Head of Solutions at Cubic, reflected during a panel session at Transport Ticketing Global 2026 on how this shift has not been a sudden leap forward, but a steady evolution shaped by more than two decades of delivery experience, learning what works and what does not.
At the heart of that evolution is trust. Digital cards build on the confidence users already place in their chosen wallet provider. Passengers trust their phone or watch to securely manage payments across many aspects of daily life, and transport benefits from that same familiarity. By tapping into platforms people already use, digital wallets reduce friction and make travel feel intuitive from the outset.

Digital wallets are becoming central to public transport. They allow passengers to start travelling instantly, without buying a separate ticket or learning a new system before their first journey. This makes life easier for regular users and visitors alike, particularly those unfamiliar with a city’s fare structure or local travel rules.
One of the reasons wallets have proven so successful is the consistent experience they offer across networks. Whether travelling at home or in a new city, passengers interact with the same wallet interface, the same gestures, and the same confirmation cues. This consistency makes new locations more accessible for users with little or no prior knowledge of the local transit agency or fare policy.
Paul highlighted how strong backend infrastructure underpins this experience. Transport systems need to treat different payment types consistently, regardless of whether a passenger taps with a physical card, a phone, or a wearable. Operators also need confidence that security, fraud protection, and resilience are built in from the start.

Several real-world examples were raised, including lessons from the SmartTrip system at WMATA and the work Cubic has delivered with partners such as Google. These experiences showed that complex deployments can succeed when the right operational planning, architecture, and partnerships are in place.
The panel acknowledged that digital wallets introduce new challenges for agencies. Infrastructure compatibility, device variation, and the need for reliable degraded mode operation all require careful planning. As wallets evolve, agencies must also consider how they manage change over time, from device refresh cycles to platform updates.
Paul spoke about the operational risks agencies face when integrating wallets more deeply into their platforms. He stressed the importance of resilience, lifecycle management, and clear architectural design. These foundations allow agencies to scale wallet use without compromising reliability or passenger confidence.
Digital wallets also support wider ambitions for public transport. They encourage multimodal travel by making it easier for passengers to move between services without worrying about tickets. They contribute to sustainability by reducing reliance on cash and paper products. They also open the door to more personalised journeys.

When paired with account‑based ticketing, wallet payments can support best fare policies, targeted subsidies, and flexible entitlement management. This keeps the experience simple for passengers, while giving operators better access to planning data and improved insight into customer behaviour.
Importantly, digital wallets remain complementary to agency apps. For many users, the wallet provides all the functionality they need for day-to-day travel. For others, agency apps continue to play a key role in journey planning, service updates, and customer support. Together, they form a balanced ecosystem that meets a wide range of passenger needs.
With more than two decades of experience, Paul placed today’s developments in context. He described how the industry has moved from closed systems to open payments and is now moving towards a future where digital wallets could become a natural part of every journey. The discussion was lively, with strong engagement across the panel and from the audience, reflecting the growing maturity of the topic.
The discussion showed that digital wallets are no longer experimental. They are becoming a core part of modern transport networks. The opportunity for agencies is significant, but so is the need for solid planning and dependable systems. As wallet platforms evolve, the focus will remain on reliability, consistency and the ability to integrate across modes and regions.
Paul’s contribution made it clear that success depends on keeping the passenger’s experience simple while managing complexity behind the scenes. When that balance is right, digital wallets help make seamless travel the default rather than the exception.
