CreditCall is one of the world’s leading providers of unattended payment services, enabling secure transactions in vending machines, car parks and for other ‘unattended’ services.
CreditCall also develops and certifies EMV Kernel software for Chip & PIN terminals deployed worldwide. Their kernels are used in both contact and contactless environments across card readers, POS, ATMs, petrol pumps, kiosks, ticketing terminals, smartphones and tablets.
After dipping a toe in the digital world, CreditCall contacted MyOxygen to develop a secure and robust iPad application to process card payments.
MyOxygen were approached by Creditcall who had worked with a previous app development company to create an iPad payment terminal that lets merchants take payments through the CreditCall payment gateway via a Bluetooth Pin pad. MyOxygen worked with the CreditCall technical team to ensure seamless integration between the app and the pin terminal.
We were provided with an existing iPhone app with some of the required functionality that CreditCall had created a couple of years before along with some example wireframes of what the new app should consist of. We took this information and created a modern design suited for use by small merchants to take payments via a bluetooth PIN pad.
The app was built upon CreditCall’s CardEaseMobile SDK which provided access to the data entered on the PIN pad and a connection with CreditCall’s servers that handled the payment processing. This SDK was used by many other development companies to benefit from the CardEase platform payment gateway.
The app was developed in such a way that it would be easily 'reskinned' for use with a specific bank or retailer. Part of this process as achieved by developing an interim library which the app would use to integrate with the CardEaseMobile SDK. This library partially abstracted away the SDK and provided commonly implemented functionality that most SDK users would need to write themselves. Whilst the library didn't provide full access to the SDK it was considered that it may be of use to certain SDK users who just needed the standard level of functionality without integrating too deeply.
We developed the app under a tight schedule in order to have the app ready in time for CreditCall to demonstrate at Apps World 2013 at Earl’s Court.
CreditCall were incredibly happy with the app and commented that we’d integrated with their API in record time, with minimal assistance.
