## Payments that cannot wait

The project started under the Dactyl Group brand, which is now part of Techmates. Roger is a Czech payment institution. It connects companies with investors and shortens long invoice maturities. The collaboration started earlier, with a mobile app for investing and for requesting invoice payment. The next step was the payments themselves. A won auction should be paid instantly, and a transfer between clients should not wait for a bank.

### Instant payments on top of the investor app

An Android app for instant direct payments for won auctions and transactions between clients. It has to build on the original investor app, and authorizing a payment has to be simple.

### PSD2 and biometric confirmation instead of waiting on a bank

The Roger Plus app, built on PSD2. A payment is confirmed with simple biometric authorization, the app connects to the original application, and the whole payment process gets faster.

> We teamed up with Dactyl to build a mobile application for us. They did their job well, so we approached them a second time with a similar request; again they delivered to requirements and on time. I can recommend Dactyl Group.
