  • Vertexon extends Change’s payments as a service offering into Oceania
  • Five of the top 10 digital payment companies1 use PaySim for their payments testing

Australian based global fintech, Change Financial (Change), which provides tailored  payment solutions, card issuing and testing to banks and fintechs today announced the official launch in  Australia of its payment’s brands:  

  • payments platform – Vertexon and
  • payment testing solution – PaySim.

Change currently manages and processes more than 16 million virtual, credit, debit and prepaid cards  worldwide, serving 146 clients in 41 countries. Clients include BDO Unibank, ME Bank and eftpos Australia. 

The pandemic has accelerated the digitisation of finance as the global appetite for ease and efficiency in  payments has increased for both the end customer/ user and provider. According to Roy Morgan’s Digital  Payments Report (26 October 2021) COVID-19 has had many impacts throughout the economy and one of  the most prominent is the increase in online retail sales. 

Change CEO Alastair Wilkie said: “Banks and fintechs can tap into immense opportunities by partnering with  Change from an integrated payment processing and card management perspective. Change can help  businesses to issue cards, digital wallets, BNPL services and access major card schemes like Mastercard,  VISA and AMEX. 

The speed, convenience, ease of use, increased security and the COVID safe nature of cashless payments has led to the FIS Global Payments Report prediction that Australia will be 98 per cent cashless by 2024. Today 90 per cent of Woolworths’ instore transactions, which captures more than 37 percent of the nation’s grocery spend, are made electronically.2 

The competition is fierce. Strong demand for cashless payments has seen the emergence of digital wallets,  and the rise of Buy Now Pay Later (BNPL). According to Federal Treasurer Josh Frydenberg3, approximately  55 million payments worth roughly $650 billion are made in Australia daily.  

Known for being simple, flexible and fast, with innovative payment solutions that have customisation, client  experience and service at their core, Change is building momentum in the Australian payments as a service,  or PaaS, space, leveraging its experience from the US market.

It is this software as a service (SaaS) model that connects existing licensed banks with modern application  programming interface (API) driven businesses and allows the end customer to use eftpos, Mastercard, Visa,  and AMEX as well as connect to payment networks via Apple Pay, Google Pay, Samsung Pay.  

“Our payments technology enables clients to launch card programs with white labelled optionality in a cost effective manner, taking care of the operational, compliance and regulatory factors. Change can assist  clients enter new and competitive markets, their payment solutions power card programs around the globe,”  Mr Wilkie remarked. 

PaySim, accelerating speed to market 

With the predicted increase in cashless payments,4 particularly as we approach the Christmas end of year  shopping season, the need for payments testing for businesses is at an all-time high. Change’s PaySim tests  companies’ payments systems to ensure they meet the capability and performance expectations of its  customers by simulating the full transaction lifecycle, enabling companies to easily complete end to end test  of its payment platforms and processes.  

PaySim’s API enables clients to automate their testing functions and integrate with their testing and quality  assurance toolsets.

In fact, five of the top 10 digital payment companies5trust PaySim for their payments testing and in Australia,  companies that want to join the eftpos network must use PaySim to certify their integration before connecting  to the local payments network.  

“PaySim reduces cost and risk by providing a faster path to market through comprehensive automated  testing solution and fraud protection for businesses by using robust testing processes that can simulate over  70,000 variations of switch types,” Mr Wilkie said.
