Paymentology has entered the Australian market through a partnership with fintech firm Constantinople.
The collaboration, announced at the Singapore Fintech Festival 2025, will see Constantinople use Paymentology’s platform for card issuing, processing, and digital wallet integration for its financial institution clients.
Founded in Sydney, Constantinople provides Banking-as-a-Service (BaaS) solutions, combining digital banking infrastructure with back-office operations including onboarding, compliance, fraud monitoring, and risk management.
Its platform supports community banks and fintechs such as Great Southern Bank and Tyro.
Through the partnership, Paymentology will handle card issuance and transaction processing across Mastercard and Visa, including Apple Pay and Google Pay tokenisation, with dedicated BINs for customisable card programmes.
The integration also includes Constantinople’s core banking system via 10x.
Di Challenor, Co-Founder of Constantinople, said:

“Constantinople’s mission is to give smaller banks and innovative fintechs access to the same leading-edge technology as big global banks. Partnering with Paymentology will allow us to launch new card programmes at pace, with the flexibility to tailor every element to our clients’ unique needs. Paymentology’s global reach ensures we can scale effortlessly beyond Australia.”
Jeff Parker, Chief Executive Officer of Paymentology, added:

“Working with Constantinople is particularly rewarding; their experienced leadership team brings a clear vision for modern, automated banking that aligns with our mission to support next-generation financial institutions.”
