e-tunity regulary develops new applications, to keep up with continuing developments.
In 2013 the mobile payment application 'WAPP' was developed. WAPP is available to download from the Apple app-store and Google play-store enabling Windesheim University students and staff members to order and pay for products with their smartphone. WAPP uses QR-Code as an format for payment information exchange. The payments app supports multiple currencies - e.g. euros and customer loyalty saving points. The advantages of WAPP are that it offers an additional sales channel, reduces the cost of cash money and card transactions in store. Website: https://www.wapp.nu

In 2013 e-tunity developed a "Virtual SEPA Engine" - a bank simulator where larger corporate customers can simulate their financial batches, in order to verify the SEPA-compatibility of their administrative systems.

In August 2014 European banks will no longer process old-style payment format files, such as the typical Dutch formats "ClieOP03" and "BTL91". At e-tunity we have developed a web application aimed at the small/medium businesses, which can convert their old-style formats into SEPA files (formats pain.001 and pain.008). Users register at go2sepa.nl, upload their files, pay-as-they-go using iDEAL to purchase conversions, and finally they download SEPA files, which can be directly sent to their banks.
