PaySim is Change Financial’s powerful payment testing and simulation software, designed to help banks, fintechs and financial institutions streamline and future proof their payment environments. With PaySim, organisations can confidently test end-to-end payment scenarios at scale, ensuring systems function correctly, remain compliant, and respond effectively to real world conditions.

Below we explore why PaySim is an essential tool for optimising your payments testing strategy.

Automation at Scale

Automation is transforming every part of the payments landscape, and testing is no exception. Traditional manual testing approaches can’t keep pace with the demands of agile delivery, frequent system updates, and complex integrations.

PaySim enables automated simulation of thousands of transactions simultaneously, far beyond what compliance-only tools offer, which typically test one transaction at a time. This allows teams to simulate a wide range of payment scenarios, from routine transactions to edge cases and failure conditions, all in a matter of minutes.

By integrating PaySim into your DevOps or QA workflows, you can:

• Run more tests, more frequently, with fewer resources
• Identify and fix issues earlier in the development lifecycle
• Accelerate deployment timelines with greater confidence

Clear Return on Investment (ROI)

Manual testing is time-intensive, error-prone, and expensive, especially for organisations with complex payment infrastructures. With PaySim, you eliminate repetitive manual test cases and reduce the need for large QA teams to run tests manually.

The platform delivers long-term ROI by:

• Supporting continuous testing, not just point-in-time compliance
• Reducing operational costs tied to regression testing and certification
• Enabling faster deployments and shorter release cycles

PaySim becomes a foundational part of your payment architecture, helping reduce overhead while improving product quality and reliability.

Regulatory Compliance

Regulatory and scheme mandates are constantly evolving. Staying compliant requires rigorous, up-to-date testing across all systems and flows.

 PaySim helps organisations:

• Validate conformance with PCI-DSS, scheme mandates, and local requirements

• Proactively adapt to rule changes without last-minute disruptions

• Avoid transaction failures, regulatory penalties, and reputational risk

 With automated testing for compliance built into your everyday workflows, your teams can focus on innovation, not chasing mandates.

Whether you’re launching a new payments product, upgrading your infrastructure, or preparing for certification, PaySim gives you the tools to test with confidence. By automating complex scenarios, reducing manual overhead, and ensuring regulatory alignment, PaySim helps banks and fintechs improve reliability, accelerate time-to-market, and reduce operational risk.

In today’s fast-paced, digital-first world, businesses are increasingly reliant on payment platforms to manage transactions, improve cash flow, and deliver seamless customer experiences. Whether you’re a start-up or an established business, selecting the right payment platform can significantly impact your growth. But with so many options available, how do you choose the right one?

At Change Financial, we understand the challenges businesses face in making this decision. Here’s a guide to help you navigate the process of choosing the best payment platform for your business.

1. Understand your business needs

Start by assessing your current and future payment requirements. Are you primarily accepting online payments, or do you need an omnichannel solution? Do you cater to a global customer base that requires multi-currency support, or is your audience local? Understanding your customer base, transaction volumes, and business goals will help narrow down the options.

Key Considerations:

• Payment methods (credit cards, prepaid cards, digital wallets, etc.)
• Frequency and volume of transactions
• Cross-border payments and currency conversions
• Recurring billing or one-time payments

 2. Security and compliance

Security is paramount in today’s digital payments landscape. Your payment platform must adhere to the highest standards of security to protect your customers’ sensitive data. Look for platforms that are PCI-DSS compliant, offer encryption, tokenisation, and fraud prevention tools.

Additionally, if you operate in industries with strict compliance regulations, ensure the platform supports these requirements, such as GDPR for EU-based businesses.

Key Considerations:

• PCI-DSS compliance
• Encryption and tokenisation
• Fraud detection and prevention features
• Industry-specific compliance (e.g., PSD2, GDPR)

 3. Costs and fees

While price should not be the only deciding factor, it’s important to understand the cost structure of the payment platform. Different platforms have various fee models, including per-transaction fees, monthly fees, setup fees, or additional costs for premium features. Choose a payment platform that offers competitive pricing without sacrificing essential features.

Key Considerations:

• Transaction fees (fixed or percentage-based)
• Monthly subscription costs
• Additional fees for features like chargeback management or currency conversion
• Scalability of pricing as your business grows

 4. User experience and ease of integration

A payment platform should provide a smooth and frictionless experience for both you and your customers. Look for platforms that offer intuitive interfaces and simple integration processes. Most platforms provide plugins for major e-commerce platforms, but it’s worth ensuring that the platform integrates well with your existing technology stack, such as accounting software or customer relationship management (CRM) tools.

Key Considerations:

• Ease of integration with existing software
• Availability of developer tools and APIs
• Quality of customer support and documentation
• User-friendly interface for end customers

 5. Scalability and flexibility

Your business is likely to grow, and your payment platform needs to scale with it. Look for a solution that can handle increasing transaction volumes and support additional features as your business evolves. Additionally, flexible platforms that allow you to customise payment flows, add new payment methods, or enter new markets will provide you with a competitive edge.

Key Considerations:

• Ability to handle higher transaction volumes
• Support for new payment methods or currencies
• Customisation options for payment flows
• Expansion capabilities for international markets

 6. Customer support and reliability

Reliable customer support can be a lifeline in case of payment issues or technical glitches. Ensure the payment platform offers robust, round-the-clock support and has a strong reputation for uptime and reliability. A platform with frequent outages or slow processing can damage your customer experience and affect your bottom line.

Key Considerations:

• Availability of 24/7 customer support
• Channels for support (phone, chat, email)
• Platform uptime and reliability record
• Access to troubleshooting and knowledge base

 Making the right choice

Selecting the right payment platform is a critical decision for your business. By focusing on your unique needs, security and compliance requirements, cost considerations, user experience, scalability, and customer support, you can find the best solution that not only meets today’s demands but also grows with your business.

At Change Financial, we’re committed to providing secure, scalable, and flexible payment solutions that empower businesses to succeed in the digital economy.

In today’s competitive payments landscape, your card issuing platform shouldn’t just support your business, it should help drive it forward. Yet many financial institutions and fintechs find themselves constrained by expensive legacy platforms that limit their ability to innovate, scale, or deliver a great customer experience.

If you’ve ever asked yourself whether your current card platform is still the right fit, here are five signs it might be time to consider a change.

1. Long Time-to-Market for New Products

If it takes months to launch a new card product or update an existing one, you’re already behind. Legacy systems often lack the flexibility, platform support or developer tools needed to move quickly, making it harder to respond to market trends or customer demands.

What to look for instead:
Platforms with modular architecture, modern APIs, and low-code integration options can dramatically reduce time-to-market, all supported by a local experienced team.

2. Limited Control Over Card Features

Can you easily configure card controls, set spend limits, or adjust merchant restrictions? Or do you have to rely on a third party every time? If you’re losing time (and money) waiting for simple changes, it’s a clear sign your platform is holding you back.

The modern alternative:
Next-gen platforms put control in your hands – no more waiting on vendors to make basic updates.

3. Poor Visibility and Reporting

In a data-driven world, delayed or incomplete transaction insights can leave you blind. If your current platform doesn’t offer real-time visibility, or if reporting is cumbersome and manual, you’re missing out on critical opportunities to improve performance and customer experience.

4. Inflexibility Across Programs or Regions

Are you juggling multiple systems to run card programs across different business lines or geographies? Outdated platforms often don’t scale well – resulting in fragmented operations and inconsistent user experiences.

A better way:
Modern issuing platforms offer unified control and global capabilities, so you can scale efficiently without compromising compliance or customer experience.

5. Your Customers Expect More

Your end users expect instant provisioning, seamless digital wallet integration, and intuitive self-service features. If your platform can’t deliver these experiences, they’ll find one that can.

What today’s users want:
Apple Pay and Google Pay integration, real-time notifications, and smart controls delivered through a card experience that feels effortless.

Future-Ready Card Issuing with Vertexon

If any of these signs sound familiar, it might be time to explore a better way forward. Vertexon by Change Financial is a modern, scalable card issuing and transaction processing platform that puts control back in your hands. From digital-first issuance to advanced spend controls and real-time program insights, Vertexon helps you launch, manage, and scale card programs, fast!

As the payments landscape continues to evolve rapidly, choosing the right payment platform is one of the most critical decisions a fintech, financial institution, or business looking to expand its product offering can make. Whether you’re launching a new card program or modernising legacy infrastructure, the platform you choose can make or break your ability to scale, comply, and compete.

Here are the key factors to consider when evaluating a payment platform:

1. Speed to Market

In an industry where first-mover advantage is everything, your platform should support rapid deployment. Look for solutions with modular architecture, low-code integration options, and ready-to-use APIs that help get your card products live in weeks, not months.

2. End-to-End Card Program Management

A truly effective platform should cover the full card lifecycle – from issuing and processing to authorisation and settlement. Managing multiple vendors for each function can lead to complexity, delays, and added cost. End-to-end platforms offer operational simplicity and better control.

3. Scalability and Flexibility

As your customer base grows, your platform should scale with you. Consider whether the platform supports multiple card types (credit, debit, prepaid), regional compliance needs, and customisable workflows that align with your growth roadmap.

4. Integration Capabilities

Your platform needs to work with your existing infrastructure. Look for developer-friendly APIs, real-time data access, and flexible sandbox environments that make integration faster and testing easier.

5. Compliance and Security

PCI DSS compliance, tokenisation, and fraud prevention features are non-negotiables in today’s environment. The right partner will proactively help you stay ahead of evolving regulations and security threats.

6. Digital Wallet Enablement

Instant provisioning to Apple Pay and Google Pay is now essential. Ensure the platform supports seamless digital wallet integration to meet modern customer expectations for convenience and security.

7. Local Support and Industry Expertise

Global capability is important but so is having local expertise. Whether you’re a fintech in Australia or a regional bank in Southeast Asia, having access to real, responsive support can make all the difference during implementation and scale.

Choosing a payment platform isn’t just about technology – it’s about finding the right partner to support your growth and innovation strategy.

If you’re looking to launch faster, reduce complexity, and future-proof your card program, now might be the time to explore how a modern Payments as a Service (PaaS) solution like Vertexon can help.

• OtherPay is pioneering safer shopping and stronger authentication with unique payment card and mobile integrated solutions.
• Change Financial and Fintech Actuator partnered with Mastercard in August 2024 to launch an incubator program to support innovation – turning bold ideas into reality.

Brisbane-based fintech, Change Financial, has today announced OtherPay as the latest participant in its Prepaid Incubator program. OtherPay is a fast-growing fintech platform revolutionising electronic payments and consumer authentication.

Focused on ending purchase and identity fraud, OtherPay aims to bridge the gap between traditional banking and the evolving needs of modern consumers. By participating in the incubator, OtherPay will introduce prepaid card functionality into its platform, enhancing its offering with new tools and features for purchase and identity protection.  

Simon Hewitt, Chief Executive & Innovations Officer at OtherPay said “We’re proud to be part of the program and to work alongside Change Financial and Fintech Actuator. This collaboration provides us with a valuable opportunity to accelerate the development and launch of our unique payment card features where we believe that innovation meets common sense and where both purchase and identity fraud can be prevented.”

In this alliance, Change Financial will issue Mastercard prepaid cards, with Fintech Actuator managing the program, aiding FinTechs with comprehensive guidance from onboarding to design and execution.  

The incubator program, which launched last year, saw Change Financial and Mastercard create an environment that empowers emerging FinTechs to innovate by running small scale prepaid card solutions to test their products in market, without the cost and extensive processes involved in launching their own custom card programs. 

Each program runs for a period of six to nine months, providing continuous support and guidance to the participating FinTechs. 

“This innovative incubator program was crafted with a vision to accelerate the growth and innovation of Australian FinTechs, ensuring they have the necessary tools and support to navigate through the initial stages of development and market testing. This latest partnership with OtherPay is this vision in action,” said Tony Sheehan, Chief Executive Officer of Change Financial.

• Change has signed a new flagship PaaS client in New Zealand – Unity Credit Union 

• Over 20,000 Unity Credit Union debit cards will be issued on Change’s Vertexon Platform 

• Change has now signed six New Zealand financial institutions, including the two largest credit unions in New Zealand, representing over 65,000 account holders  

Change Financial Limited (Change), a leading ASX listed (CCA) Australian payments fintech, has signed a new Payments as a Service (PaaS) contract with Unity Credit Union (Unity), one of the largest credit unions in New Zealand, to provide direct issuing, processing and card management solutions via its Vertexon platform. 

Change has commenced the onboarding process, with Unity expecting to have approximately 20,000 debit cards, in circulation by December.   

Change Financial CEO, Tony Sheehan said, “It’s great to see a large and well-respected credit union like Unity choose Change Financial in New Zealand for fast, reliable, and seamless consumer card solutions. We have made significant investment in our platform and like our other financial institution clients in New Zealand, Unity is making the switch to Change to take advantage of advanced features and services that allow them to deliver superior payments experiences to their customers.  

“We now have a significant presence in the New Zealand market with our platform servicing the two largest credit unions.” 

“With our Vertexon platform fully operational, it is highly encouraging to secure another significant client as we build scale and momentum.” Mr Sheehan said. 

Unity will use Change partner Finzsoft Solutions Limited (Finzsoft) as their core banking platform provider, so given these synergies the development work for the onboarding process has already substantially been completed, creating immediate efficiencies for all parties. The addition of another credit union to Change’s suite of customers throughout the New Zealand market is further recognition of the strong partnership and combined value offering of Change and Finzsoft.  

Unity Credit Union CFO and acting CEO, Bruce Morrin said, “Change’s product and service offering will enable us to improve the payments experience for our customers. From being able to offer enhanced features such as Apple Pay and Google Pay, to having superior controls that reduce fraud and other operational costs, we can provide modern card features that rival the major banks, a significant and unique value proposition for non-bank financial institutions like us.” 

Change has now secured the two largest credit unions in NZ as Vertexon PaaS clients in addition to several other NZ financial institutions and fintechs. Once the migration with Unity is complete, it will take the total number of account holders serviced via the Vertexon platform within New Zealand to over 65,000. 

Mr Sheehan added, “Change Financial is continuing to expand its presence within the New Zealand market, which comes at a time when it is still quite difficult for smaller to medium sized New Zealand businesses to access consumer card programs, beyond those offered by major banks. By addressing this gap in the market, we will continue to build our presence whilst also improving the payments experience for consumers.” 

When deciding on a new card payment platform, it’s crucial to consider the technical features that will ensure a seamless, convenient and secure experience. Here are five essential features to prioritise when evaluating card payment platforms.

Payment Platform Features

Integration with Digital Wallets: 

As digital wallet platforms like Apple Pay, Google Pay, and Samsung Pay gain popularity, it’s important to choose a card payment platform that seamlessly integrates with these systems. This integration allows customers to make payments using their digital wallet, offering both convenience and enhanced security compared to traditional physical cards.

APIs for Mobile Development and Integration:

If you’re a developer or plan to incorporate the payment platform into your mobile or web-based application, look for a platform that provides robust APIs (Application Programming Interfaces). These APIs enable easy integration, allowing you to customise the payment experience and create a seamless connection within your app.

Cardholder Self-Service:

Empower cardholders with greater control and convenience by opting for a payment platform that offers self-service features:

• PIN Reset: Allow users to reset their PIN securely.
• Card Blocking: Enable cardholders to block a lost or stolen card immediately.
• Temporary Card Pausing: Let users lock their card temporarily—for those times when they need a break from card usage.

These features prove especially valuable during emergencies or when managing card security.

Security and Fraud Protection:

Prioritise a payment platform that goes the extra mile in safeguarding transactions. Key security measures include:

• 3D Secure (3DS): Implement this security protocol to protect online card transactions.
• Encrypted Data Transmission: Ensure that sensitive information remains confidential during communication.
• Secure Servers: Host transactions on secure servers to prevent unauthorised access.
• Regular Security Updates: Stay ahead of potential threats by keeping security protocols up to date.

Virtual Cards:

Another useful feature to consider is the ability to create virtual cards. Virtual cards are digital versions of physical cards that can be used for online transactions. Virtual cards have several advantages including:

• Organised Finances: Create separate virtual cards for different purposes (e.g., online shopping, family expenses).
• Loss and Theft Prevention: Virtual cards cannot be physically lost or stolen.
